Your mostly correct about everything, except in your little rent about centimeters which makes no sense at all and curiously seems to miss the whole point of the metric system. It shows you live in a country that uses the imperial system ahaha. The whole point is that you can use whatever you want depending on the accuracy you want. mm, cm, dm, m or km... It doesn't matter. If you tell me 300 milimeters, I know you're talking about 30 cm or 3 dm, 0.3m... And I'm not gonna say to you that something is at 3000000 mm away ; I'll just say 3 km. That's the whole point, they're all just decimals of a meter (milli : thousands, centi : hundreds, deci : tens, meter : actual unit, kilo : a thousand). We don't care which unit is on the ruler, we already know since little school what all these are. The fact they are marked incorrectly in the US doesn't mean it's complex... You're overthinking it. It just means they're marked incorrectly ahaha But then again, maybe it's because I speak French and the names of the units make more sense in our language... But yeah we don't know anything about it. (We literally created it tho lol...)

centimeters are just fine... we SI system users are perfectly used to them and are no different to us as millimeters.... that's because meter is the primary unit of length and CENTImeters are alike MILLImeters, smaller parts of meter! centimeter is, as its name "centi" says, one hundredth part of a meter, while millimeter is one thousandth parts of a meter.... we also don't have a problem with DECI prefix (like, decimeter), which, as the origin of the word suggests, just mean one tenth part of the meter...

This guy may speak only for an engineering public working in construction. But what he says doesn't make sense in a broader view. The SI knows only meters, kilograms, seconds, Amperes, Kelvin degrees, moles and candelas. All other units are derived from these seven. So, only meters. If you need big figures, you can use prefixes or powers of 10. Same for small figures. There is no such unit as the millimeter: it is just a convenient way to express meters for small distances. Same for the gram. In Europe, for everyday life, we use the most convenient prefix depending on the context. The distance between two cities is better expressed in km than in mm, like you would find convenient to use GB instead of 000,000,000 bytes for a hard drive. And the French do not use the bizarre convention of the double decimal point as presented. However, we sometimes use a point to separate thousands, just like you use commas. Sorry to sound maybe impolite, but this guy is definitely too arrogant and not even right.

USA has applied metric in many areas. Military especially - mostly due to NATO standardization which is based around metric system. Hence the US soldiers will say 556 (5.56x45) or 762 (7.62x51mm) for rifle ammo, pilots say 20 or 30 mike mike (20mm or 30mm aircraft guns), one-ought-five (105) for 105mm or one-fifty five (155) for 155mm howitzer shells. 120 (one-twenty) or 82 - you guessed it: 120 and 82mm like mortar rounds. 9mil for 9mm rounds. Thing is, there are many benefits of going metric, but this process has to be adressed in USA seriously if they really want to switch i.e. it needs to start in primary school, and follow through education (highschool, colleague etc). But once you have educated people learned in metric, they can apply their knowledge anywhere in the world. Especially precise engineering - say you need micron precision for something as thin as human hair. Metric states human hair is 70microns (+/- 20 microns). Imperial states it's 0.001 inch that is 25.4 microns. See the difference? Almost three times. And there are such important small tolerances in precise engineering you know where microns do matter.

One small thing that has always annoyed me (a EU citizen who grew up in metric and otherwise loves it) is that the base units don't nicely align. A liter of water doesn't weigh a gram, and it also doesn't fit into a cubic meter. It weighs a kilogram and fits into a cubic decimeter (1/10th of a meter, or 1/1000th of a cubic meter). I realize that it's probably for convenience, aince the base units are chosen depending on how often they're used or whatever, but it still kinda triggers my OCD me that they're misaligned every time I think about it beyond the surface level.

I fully understand why would you want to use millimeters in technical drawings and stuff but in every day life centimeter rules over millimeters and this comes from a place that is fully metric. Interestingly enough centi is only used in length measurements, weight and volume do not use it. It's milli or the base unit.

In Hexadecimal, the name "10" IS the quantity of 16 counted in decimal. You have mixed decimal and hexadecimal in the same equation, that won't work. Hexadecimal(base 16) is better than decimal but Duodecimal(base 12) is better than hexadecimal for most things. That is because The number twelve, is a composite number and is the smallest number with the factors (2, 3, 4, 6), and the smallest to include as factors all four numbers (1 to 4). That is why 12 inches in the foot is superior to metric 10. What ever the base you choose 10 x 10 is STILL 100.

The use of commas is idiotic, I'm sure they did that just to be "different", very french.

OK. 880mm x 1562mm is easy enough to work with in the brain. What about the total house length of 40 feet? No, not 12,192mm...one would say "12 point 192 meters". And centimeters have their place as well while we're at it. What it comes down to, is the common unit of measure one would use is dependent on the relative size, scale, industry and level of precision required. The good thing is that it is easy to move a decimal point up or down when converting because the prefixes for weight, distance and volume all mean the same thing.

I don't know it anyone will read this comment and If anyone already wrote it in a comment but if so, I didn't found a comment saying anything like it. So I do it myself. He obviously bashes so hard against centimeter and sounds like he want to completely remove it from everywhere. But like in many comments here pointed out, that is just dumb and doesn't work. And switching from mm to cm is so easy that people who had only the metric their whole live can do it without thinking at all. No the problem he has is something completely different. The first problem is pretty much obviously the imperial system because it's just so bad. Every time conversion between those two happens, errors will happen at some point. And this ties in to the second Problem: A standard label on tools with the exact same purpose. Here comes the ruler think he speaks about. Because like he showed, sometimes its mm and sometimes its cm. But the think here is, it depents on who gets that ruler into his hand. A American is easly confused because he has probaly no idea what of the lines is the mm and what is the cm. But I never heard of someone so far that he couldn't use a ruler because he doesn't know what is for what. Because if you grow up with Metric, you immeidately recognize the size difference and know what is meant to be mm and what cm. Similar is it at other things. And that is because they learned it from childhood on. It's so much a part of them that they don't need to think about it at all. So while he bashes so much against cm, what he realy wants is to essentialy create a norm for what part of the metric system comes on what tools. And every country using Metric should at least use that norm. Oh and those few countrys with imperial should realy switch to Metric because Imperial is just so bad compared to Metric, it causes death and makes is harder unnecessarily.

Nobody uses millimeter because we don't need to, just make any measurement in millimeter that ends in 0 and and then you have centimeters. Smaller numbers are not to be avoided, a school kid can figure out a ruler because they know how to count to ten not to a thousand, and if a first grader can, then so can you. Just choose a millimeter measurement with a 0 at the end, if you are constructing then it's your choice if you want to make it so that you need to pay surgical precision to every brick and column, or if you can just use a ruler. Or better yet just use centimeters and add a 0 when the millimeter police comes around. And also i have never heard the height of a person being described by using millimeters because it would be useless, that's the perk of metric you only use the one you care. If you are measuring the distance between between two cities you need kilometers because that what's appropriate, what you are saying, is like measuring the hour by the second, it doesn't make sense.

Why do you say "Nobody uses millimeter because we don't need to"? Who are YOU to say that "nobody" does anything - and, where do YOU reside? I can assure that the whole of the building and construction industry in Australia (and in the UK) uses the "millimetre" as the basic unit of construction. In the Australian Standard AS 1155-1974 "Metric Units for Use in the Construction Industry", it was specified that "The metric units for linear measurement in building and construction will be the metre (m) and the millimetre (mm), with the kilometre (km) being used where required. This will apply to all sectors of the industry, and the centimetre (cm) shall not be used. … the centimetre should not be used in any calculation and it should never be written down". The US "METRIC DESIGN GUIDE" (PBS-PQ260) (Page 10) states "Centimeters (cm) Centimeters are typically not used in U.S. specifications. This is consistent with the recommendations of AIA and the American Society of Testing Materials (ASTM). Centimeters are not used in major codes. Use of centimeters leads to extensive usage of decimal points and confusion to new readers. Millimeters (mm) SI specifications have used mm for almost all measurements, even large ones.

The reference for the above is at www.gsa.gov/cdnstatic/Metric_Design_Guide_PQ_-_260.pdf By the way, one hour is 3600 seconds.

You wrote “how dare you say that early adopters were wrong because you don't like the notation at that time, when it took 200 years for Australia to make the switch ?” In writing this you appear to be reacting in a manner akin to those in the USA who believe that their historic “Customary Measures” are superior and cannot be improved. The Metric System was introduced in 1795, with just six prefixes (representing from 10−³ to 10³). (It MAY be that the original metric system was intended to have a new prefix for every additional power of ten [for both positive and negative powers. ] However, this became too cumbersome so the “International Bureau of Weights and Measures” (BIPM) has since used only the powers that were multiples of 10³ (and 10−³). Unfortunately, the four non-10³ prefixes were never dropped.) Two more (10³ based) prefixes were not introduced until (78 years later) in 1873, four more (10³ based) prefixes (87 years later) in 1960, two more (10−³ based) prefixes in 1964, two more (10³ based) prefixes in 1975 and four more (10³ based) prefixes in 1991. (en.wikipedia.org/wiki/Metric_prefix) In practice, the only non-10³ (or non-10−³) based SI terms now in general use are the centimetre, the hectopascal (both of which can be “avoided”) and the hectare, with the centilitre (which can be avoided) in use in “older” metric countries. It has been remarked that, were the "Metric System" to be invented today, it is probable that the non-10³ based prefixes would NOT be introduced. (See www.metricationmatters.com/docs/centimetresORmillimetres.pdf and themetricmaven.com/naughtins-laws/) The average citizen in countries which actually adopted SI since the 1970s, in general, does NOT use non-10³ based terms (except for those few mentioned above). (Many would never have heard of them - at least, since school - and certainly do not NEED to use them in their home countries.) You should note that non-10³ based prefixes are NEVER used in science nor in association with "electrical" Units, such as Watts, Ohms, Amps, Volts etc. You will NEVER see a reference to hectowatts, dekaohms, deciamps, centivolts etc., although they are legitimate "metric" terms These are reasons why The Metric System Is Better By A Thousand.

Unfortunately, (at 5:50) he did not display the full quote from (Australian) Standard AS 1155-1974 "Metric Units for Use in the Construction Industry", which specified the use of millimetres as the small unit for the metrication transition. This is as follows: "The metric units for linear measurement in building and construction will be the metre (m) and the millimetre (mm), with the kilometre (km) being used where required. This will apply to all sectors of the industry, and the centimetre (cm) shall not be used. … the centimetre should not be used in any calculation and it should never be written down" (en.wikipedia.org/wiki/Metrication_in_Australia ) You should note that this does NOT preclude the use of the metre and kilometre - just the centimetre (and, by implication, the decimetre, decametre, and hectometre.) (Hence, the spurious accuracy in your first comment was not entirely appropriate !) You might also note that the US Metric Design Guide (www.gsa.gov/cdnstatic/Metric_Design_Guide_PQ_-_260.pdf ) also specifies "Centimeters are typically not used in U.S. specifications. This is consistent with the recommendations of AIA and the American Society of Testing Materials (ASTM). Centimeters are not used in major codes" and "SI drawings preferably use only millimeters (mm) to avoid fractions and to eliminate the repetitious suffix." "SI specifications have used mm for almost all measurements, even large ones. Use of mm is consistent with dimensions in major codes, such as the National Building Code (Building Officials and Code Administrators International, Inc.) and the National Electric Code (National Fire Protection Association).

@@FrodoOne1 Ok, I was joking a bit. There is nothing telling me that this lecture was directed towards people from the construction industry, only. If it was, then OK, but if it was directed towards a general audience, it was too narrow. The beauty of the metric system, is its flexibility. The use of cm or dm, outside contsruction, is in many cases more suitable than only using mm. Accuracy isn't always that importaint, meaning for instance 27 cm isn't the same as 270 mm. When it comes to units for energy, I totally disagree with his view. Energy comes in many different shapes and forms. In some cases it can be right to convert them into one unit ,Joule, if you want to compare them, but otherwise it is better to keep them.

@@th5841 To say that "There is nothing telling me that this lecture was directed towards people from the construction industry." is quite true. While you wrote "The beauty of the metric system, is its flexibility." is true. "The use of cm or dm, outside construction, is in many cases more suitable than only using mm.", is NOT so. The “point” of eschewing the non-1000 metric prefixes SHOULD be ” belabored”. Those heca, deca, deci and centi prefixes are those which most “get in the way” of the complete adoption of SI (in the 6% of the world that does not yet use it to their exclusion of any other system.) I do wonder why you would write that "27 cm isn't the same as 270 mm" Since "Energy" comes in many different shapes and forms" why would it not be preferable to convert any reference to "Energy" into just one just one form/nomenclature - such as the Joule ? While you wrote "Energy comes in many different shapes and forms. In some cases it can be right to convert them into one unit ,Joule, if you want to compare them, but otherwise it is better to keep them." (Please explain.)

@@FrodoOne1 It is good that we agree on some points. Let me comment your comments. I will use cm when accuracy beyond cm is not needed. - How tall are you? - I am 1-88. I don't know and care about the excact mm, and we all know that we are tallest in the morning, and then our spine will get shorter during the day, so why bother? I could have said 1 m and 88 cm or 188 cm, but we know what I am talking about, so I'll remove the obvious parts. So if I said "I am 1880 mm, that is just not true, I will explain in the next point. 27 cm isn't the same as 270 mm because 27 cm in real life is anything between 265 and 274 mm, while 270 mm is anything between 269.5 and 270.4 mm. There you have the difference. There was a funny excample of this lack of understanding in a journalist's report from the Iraq war. They said: "USA has around 2000 airplains participating while the UK has 33. The total of 2033 airplains." Energy: Kinetic energy E=0.5*m*v² with unit Nm (0.5 * mass in kg * squared velocity in m/s) Potential energy E=m*g*h with unit Nm (mass in kg * gravitational acceleration in m/s² * height abow ground in m) 1 Nm = 1 J. Nm is used to show what kind of energy it is. Electric energy E=P*t with unit Wh (power in W * t in hours) 1 Wh = 3.6 kJ When you use J in electric energy, you use the same formula as for Wh, but it is with the unit second, not hour. You can argue that s should be used, but h is prefered because energy is accumulated over time, and seconds isn't an interesting unit in that sence. Heat energy E has the unit J, but I can't remember the formula for this. Can be googled if you like.

@@FrodoOne1 Wanting to take away cm, dm and so on in our daily life, is just like saying "we don't need this word, because it is just a synonym to another word, and knowing and using two words that means the same is just a waste of time and brain. If you don't want to use cm, then fine, but telling others to stop using it is just... silly tbh.

Describing metric while you are used to imperial is not feast. This guy win my respect even tho all metric all the same as long as you understand it. There is no bad unit.

What's bad with centimeters and so even decimeters and meters? 1000 Mm = 100 Cm = 10 Dm = 1 M. 3 just as simple ways to breakdown each measurement (higher or lower). Same with distance and volume. If you like a Mm ruler measuering 10-20-30-40-50 Mm etc you can read it as 1-2-3-4-5 Cm knowing it's 10 Mm in a Cm. And when you reach 10 Cm just like 100 Mm you've got 1 Dm. Less numbers to write down but just as easy to grasp and write as you see fit. I totally get the argument for only using millimeters, but there's good reasons for using Cm, Dm and M too.
