The real deal with the metric system is that everything is interconnected. 1cm^3 = 1ml = 1g Multiplied by 1000 you get 1dm^3 = 1l = 1kg Multipied again by 1000 you get 1m^3 = 1kl = 1t To put it simply if you make a water tank that is 1m by 1m by 1m (1m^3) you'll easily know that it has a volume of 1000 litres (1kl) and it will require to be sturdy enough to support 1000kg (a metric ton).

Actually, the *IMPERIAL* system of units were designed around very definite objective quantities -- the Imperial Gallon, for example, is the volume of 10 pounds of ale. The *U.S. CUSTOMARY* units are older, and originally do derive from approximate measurements such as the length of your foot, but today are rigidly defined in terms of Metric units (e.g. a U.S. customary inch is defined as exactly 2.54 centimeters).

For me personally, I only really encounter inches in woodworking. The most important thing of course is that everyone understands what measurement and unit you are talking about. You clearly demonstrate the importance of this with your examples of "tons". (In Norway we sadly don't use any kind of convenient short hand like "thou", that I'm aware of. Instead we mostly say the whole phrase. "10 thou (10 thousands of an inch)" = "ti tusendels tomme" = literally " ten thousand parts of a thumb". Though, "thumb" is actually "tommel".

This is a historical artifact, however, and has nothing to do with the Celsius scale in use today. Fahrenheit's original temperature scale, likewise, doesn't match the modern one.

There are two units which SOUND like a root vegetable: gemstones are weighed in CARATS, which are equivalent to 200 milligrams, thus 5 carats in a gram. But the PURITY of gold jewelry in measure in KARATS. A karat of gold purity is 1/24 pure gold. Thus, 10 Karat gold, written 10K, means 10/24 gold by weight, so a 10k ring weighing 24 grams contains only 10 grams of gold, alloyed with 14 grams of other metals. And there is another kind of foot, known as the METRICAL foot, in poetry. This is a repetition of a fixed number of syllables containing a fixed stress pattern. A foot of two syllables with the stress on the second syllable is called an IAMB, or IAMBIC foot (if MU-sic BE the FOOD of LOVE, play ON), for example, and a line with 5 iambic feet is called Iambic Pentameter.

Oz is about 100mL and how big an inch is (about 2.5cm) but other than that I have issues with things like quarts, US gallons, different types of weights etc. But you've explained that to me. It just amazes me that people find it easy to use all these units.

It all seems very strange if you're not familiar with it, but if you grew up with it, it's not hard to understand and get accustomed to. Is the U.S. Customary system as good as the Metric system? Well, no, but it's not nearly as bad as some people make it out to be. It's certainly good enough for everyday, nonscientific measurements. And in many cases, the size of the units in the U.S. Customary system are more convenient than metric units. For example, feet and inches are quite handy for measuring small to medium size objects, while centimeters are a bit too small and meters are a bit too large. Sometimes, inches and feet are "just right". 🙂 And the U.S. Customary system has the advantage of being familiar and universally used within the United States, which is a large country. (Being a very large country, the people who live in the U.S. mostly only deal with other people in the U.S. Thus, the benefits of using an international measurement system don't exist for us Americans.)

I'm glad Australia went completely metric decades before I was even born, and there was no half-holding on to the old system.. ..well, actually, we still have to deal with Imperial measurements here and there because of other countries (rolls eyes at America) because some 'standard' sizes of things are Imperial. One example is that all my cameras use a 1/4 inch screw to mount onto a tripod. Yuck!

The screw in your camera will not change and it is likely that if a descendant of yours were to buy a camera in 100 years time the mount on the camera would still be the same screw size but would probably be referred to as 6 mm. A similar situation exists with pipes and their fittings. If you now go into a hardware store to buy a pipe fitting you will find them labeled for use on 12 mm, 19 mm, 25 mm, 32 mm pipe etc. However, these items are of EXACTLY the same dimensions as their predecessors, which were labeled 1/2 inch, 3/4 inch, 1 inch, 1 1/4 inch etc., which is a "soft" conversion. This has to be, since you may need the new item to fit the existing old installation. Standard gauge rail lines are 4 Feet, 8 1/2 inches apart. That is 1.435 metres. They have to stay that way!

FrodoOne1 A 'soft conversion' doesn't work for everything though since a 1/4 inch is 6.35mm which means a 6mm tool is too small and a 7mm tool is too big - you can't label it differently and you still need a proper imperial tool unless you want to strip the bolt. I know we have to keep old standards like the rail line gauges, but that's what I find 'yuck' because if we made it up now then instead of 1.435 meters we'd make it a nice round number such as 1.4 or 1.5 meters.

Daniel Jacob The only "tool" that your camera screw needs is the paired Thumb and Forefinger of the human operator against the integral knurled knob, which was designed for this purpose. The specification of the "thread" is immaterial, as long as it fits YOUR camera and all past and future cameras. Whitworth (and other) nuts and bolts are still made to the same specifications as they ever were, except that the manufactures describe these (in-house) in metric terms. However, they are sold in terms of their "Imperial" width but by their metric length. Pipe fittings are made to the same specifications as they ever were, except these specifications have also been translated (in-house) into SI terms. However, they are now sold with the diameter described in the closest metric equivalent to the "Imperial”' diameter. This is a "soft" conversion. If you need to work on equipment manufactured before about 1980 (or in the USA) you may need to obtain/retain the appropriate spanners and sockets. However, for screwdrivers it is probably more important to obtain the appropriate specialised and "tamper-proof" varieties, of which there are many. There is no particular virtue in a "nice round number". The "Standard" rail gauge of 4 foot, 8 1/2 inches (1435 mm) is NOT exactly a "nice round number". You may regard as such the "Victorian" Broad-gauge of 5 foot 3 inches (which now translates to 1600 mm). (Looking at those dimensions, I now wonder if someone back in the 19th Century could see into the future - or was it just dumb luck?) The gauge of 3 foot 6 inches (which you may regard as a “nice round number”) used in some other States, translates as 1067 mm, again, not a "nice round number". I don't think that many people care about the size of a rail gauge, as long as the trains work safely, efficiently and comfortably - in that order. All other considerations being equal, the broader the gauge the more comfortable it is likely to be. However, there are economic considerations and it appears that the world has standardized on 4 Foot, 8 1/2 inches (1435 mm) whether you or I like it or not. Here is something for you to worry about in the future If/when the USA converts to the metric system (SI), it is likely that the different levels at which planes fly will be converted from 1000 feet to 300 metres - which is the nearest "nice round number" However, 1000 feet is actually 304.8 metres. By the time you get to 30,000 feet, the difference between (30 * 1000) 30,000 feet and (30 * 300) 9000 metres is 144 metres (567 Feet). In the unlikely event that a "soft" conversion is used by ALL airlines and Air Forces, there will not be any problem. If there is a "hard" conversion (at EXACTLY the same time) by ALL airlines and Air Forces, there will not be any problem. If there is a combination of either of these scenarios, or miss-timing of the latter, there is likely to be SIGNIFICANT problems for high flying aircraft. Just visualise two aircraft approaching each other from opposite directions separated in height by only about 1.5 the length of the 100 metre track in an Olympic stadium!

@yongodharma To be fair, the Celsius temperature scale really isn't that much more usseful -- or less ambiguous -- than the Fahrenheit scale. In both cases, the numbers are more-or-less arbitrary; memosizing "75 degrees Fahrenheit" for room temperature is no different from memorizing "24 degrees Celsius". The only place where Celsius has an advantage is if you want to quickly deduce how close a temperature is to the freezing or boiling point of water.

CORRECTION: At 7:08, I say that the British/Imperial nautical mile is 6080 feet. This is misleading. The British nautical mile -- more properly called the "Admiralty measured mile" -- is exactly 6080 *imperial* feet. The imperial foot is ever-so-slightly shorter than the current international foot, by about 1.7 parts per million. In *international feet*, 1 British/Imperial nautical mile works out to 6079.979 feet.

You're not the first person to bring up this objection to the metric system. It's based around powers of 10, rather than powers of 2 or 6 or 12 or 30, because humans use base 10 for counting -- but only because we happen to have 10 fingers and thumbs. However, most practical applications that call for dividing a unit into thirds are usually only interested in approximations anyway. A recipe that calls for 1/3 of a cup of milk usually works fine with 3/8 cup, for example.

"Avoirdupois" is actually "avoir du poids" which can be translated by "having some weight". I must confess it's the first time I hear about it. In fact, the metric system was invented precisely to get rid of all these old weights and measures in France, who could be different from one city to another or from one trade to another. There were complaints dating back to the middle ages (and probably even sooner).

Just, one comment; the nautical mile is now defined as 1852 m (just as US and UK measurements are defined by metrics), but this is a navigation tool originating from one minute of latitude on the base 60 world grid.

Reuel T, this latest complaint of yours seems to be concerned with the fact that a metric-sized tool made to be in the same "size ballpark" as an inches-sized tool is slightly smaller. A 25 cm circular saw is NOT SUPPOSED to be the same size as a 10 inch circular saw. It's supposed to be 25 cm. There is nothing inherent in the metric system that would prevent a tool manufacturer from producing a 25.4 cm circular saw blade or a 6.5 mm router bit.

You're not the first to suggest that the metric system, while an improvement over the old U.S. customary units, is still lacking. Particle physicists, for example, use a system called "Planck units," in which the basic constants of the universe -- the speed of light, the reduced Planck constant, Newton's gravitational constat, the Coulomb constant, and the Boltzmann constant -- are all set equal to 1. This results in some weird base units; the Planck mass works out to 21.7651 micrograms.

I shake my head in disbelief not only at the craziness of those units of measurements, but that Americans have been 'trying' to change over for over a century and still haven't! If I remember correctly the country I'm from changed over in the 1960's and we haven't looked back since. We are a 3rd world country! As for those that say that they will have issues with old instructions (for units of measure) for example baking. Most things we have, are stamped with both measurements, on the things we measure with. (But if it doesn't, there are also conversion charts of the more common measurements.) I have noticed that thier availability has become less in some areas for measuring things over the last few years. But it has now been more than 50 years since converting. Most people do not need them anymore. Also by using the Metric system, that 99% of the rest of the world is using. It will save money due to errors not been made. Like loosing a multi-million dollar probe because somebody got the measurements wrong. The trick is changing over and not going back, no matter who grumbles. It's like going for a swim. Dipping your toes in the water saying that it is too cold and pulling them out again. Will not get you in the water. You need to jump in and let the shock of the cold water hit you for a moment or two. After that your body adjusts and you are able to have an enjoyable swim. It is the same with this change over. Just do it.

-- "If I remember correctly, the country I'm from changed over in the 1960's and we haven't looked back since. We are a 3rd world country!" Well, that may be a big part of the issue. A huge, well-developed nation like the US. has a large population and an enormous amount of infrastructure and industry built on the old units. That makes it harder to change, compared to a small, poorly-developed country that doesn't have all that stuff. Also, because of America's enormous size and its relative geographical isolation (we only share a border with two other countries), most people in the U.S. simply don't have to deal with the measurement systems of other countries. So there just isn't a compelling reason to change -- the old units actually work quite well for everyday use. While at the same time, the inconvenience in trying to change is substantial. So with a large detriment and no great benefit from changing systems, it's no surprise at all that the general population of the U.S. hasn't embraced the metric system. (But note that the fields of science, engineering, and medicine have.) (And yes, I know about the famous Mars orbiter fiasco. Being squarely in the field of science and engineering, Lockheed Martin absolutely *_should_* have been using metric units all along. When I read about that mishap 18 years ago, I was shocked to learn that Lockheed Martin wasn't using metric units for its aerospace designs. WTF??? I couldn't believe it. I can't think of any endeavor where metric units would be more appropriate. Orbital trajectories and rocket thrust is all about math & physics, which is _precisely_ what the SI system is designed for. It's truly mind-boggling that L-M wasn't using SI/metric units for designing and building *_spacecraft,_* of all things. We're not talking about baking loaves of bread here. But that was 18 years ago, and I'm sure they've learned their lesson!) But as for ordinary everyday personal and household use (not international commerce or science or engineering), the old customary units are actually quite handy. I *do* like your "jumping in to the swimming pool" analogy, though. :-)
