Something that people forget is how much easier it is, with metric system, to create an idea in your head about the size of something, regardless of it being displayed in meters, cm or mm. You automatically know that a 101cm wide object won't fit in a 1m hole while it's not as obvious that 39,7 inches won't fit 3,28 feet! Nice video!

While 100 maintains the ease for dividing into halves and quarters, 60 has the advantage of being also cleanly divided into thirds and sixths. Which, let's face it, while we don't use 6ths all that often, a 20 minute break can really hit the spot.

I'm moderately sane, and tend to prefer U.S. customary ( pound force, slug mass, foot length) units for three big reasons: 1. Compound units generally are not named. Pressure is pounds per square foot not Pascals, or Barr, or Torr ... 2. Base 10 is a pretty lousy choice, the world in not base 10, also throwing in the the prefixes makes computation harder. 3. Units are sized better. In SI the base mass unit is Kg because grams are too small, a standard liter is 0.1 meters cubed because a cubic meter is too much big. Both systems have issues with temperature and obsolete units mucking about.

the first time, in school, you understand that measuring only ONE edge of a cube gives you not only the volume but the WEIGHT a full tank of any liquid (-ish, ok, i know oil is lighter than water...) , it's more than convincing.

I'm a child of the UK conversion era. Taught metric and imperial in school and released into the workplace to work under old school electricians with cable and conduit that had recently been converted I learned to be able to switch from one to the other. The best part of metric is how the different measures work together. A one metre (1000mm) cube of water is 1000 litres and weighs 1 tonne. Tip for Americans getting used to metric, try to move up to the next level of measurement instead of sticking to millimetres. For example: 10mm is 1 centimetre, 1000 mm is 1 metre. Scaling from drawings (Blueprints) is much easier with metric too.

Centi well always be in increments of 100 of the base unit. Those are in the negative scale, so going lower than the base unit. there is also SI prefixes for going greater than the base unit.

6:09 - That's not "weird", that's pretty much the standard in most of the world. It's pointless to have something marked "10-20-30-40-etc.", if the last digit is *always 0,* then it's wasted, it adds no useful information. The whole point of the SI ("metric") system is that you *change the unit prefix* to the relevant magnitude. So if you're only going to mark it every 10 mm, you switch to cm and drop the useless zero.

You'll have to argue that out, as the invention of the first folding ruler is credited by most authorities to Anton Ullrich in 1851, whilst the Karl Hilmer version dates from 1883. Most probably, these were different designs. It is not unusual for there to be competing claims, such as who invented the light bulb? However, the Stabilo folding ruler, based on an Ullrich patent for a spring hinge did not appear until 1888

But you would be surprised to find out how many times a dozen comes in handy. Dividing by 3? With base 10 you have a never ending and unresolvable stream of 3's. While base 12 gives you an nice even 4. Which comes in handy when squaring things up since a unit square angle - that is a tringle with a right angle - can be precisely defined with a tringle with sides that are 3, 4 units long. And what is 3x4? Oh yea, it is 12 not 10. All of which works out perfectly if you divide 1 into 12 equal parts rather than 10 equal parts for a Unit square of 1 x 1 4/12 With a Hypotenuse of 1 8/12ths On the other hand if you use 10 to calculate your unit square you get a pathetic and unworkable 2.5 x 3.33333333... On and on forever x 4.16666666666..... On and on forever. Considering that squares are rather important for structural integrity... well, I guess you can get an idea of where to stuff your pithy base 10. Just face it already. As long as we are using base10, fractions will always be a necessity to cover the spots base 10 cannot. Also, the metric system does not add any value other than renaming numbers. Why say 1 Meter when you can just say 100 centimeters. The standard foot and inch system have specific relationships to each other for specific functions. It is just pathetic that so many people cant get their head around it.

​@@makersmark5607 An unresolvable stream of 3's has no influence at all on the building process unless you are doing some work which requires some very high level of precision. You round up or down to the closest millimeter and you have a very accurate measurement. More accurate than most machines are capable of producing. For calculating things it doesn't complicate either since dividing by ten and rounding up or down is easily done without the use of a calculator. Also, a lot of building materials here are made in dimensions which are dividable by 3. Most common sizes used are 900mm, 1200mm and 2400mm so this solves the problem as well. Also, if imperial was so much better to create structural sound things, wouldn't you think NASA and the likes would use it as well but for some reason they use metric to do the most advance things human beings are capable of achieving.

@@makersmark5607 as someone who uses both systems depending what I’m doing you started your argument well and included some good points. But your argument became a biased opinion when with your final statement, saying 1 meter instead of 100 cm is no different then saying the same for feet and inches and they both serve the same purpose to reflect the accuracy required given the scale your working with. Also the base 10 terms date back to Latin and also hold different meanings and links they are also a language reflection of Roman numerals a century is 100. In terms of relationships they also exist in the same ways i.e 1ml has the volume of 1mm3. Where it often gets twisted is that common place metric actually accounts for some of the simplification conventions you spoke of like using degrees instead of radians. In my opinion at the end of the day metric is the way forward even when as an engineer I know that somethings work better in imperial and some work better in metric but we as engineers are a small part of the population and metric makes the math so much easier for all those in the world who are not.

IMO the best thing about Metric is how easy it is to put lengths, volume and mass into relation. Like, if somene came along and told you there is a box that has a base of 30 by 30 centimeters and a height of 20 centimeters all you do is 30x30x20 = 18000 cubic centimeters (easy to calculate by head), then you divide it by 1000 (1000 cause we are calculating in cubic units) to get cubic decimeters and boom, cubic centimeters equals liters. So you know the amount of liters it fits without needing a calculator. And it gets better, as one liter of water equals 1 kilogram you know also that that if you fill that box with water it will weight 18 kilograms. I honestly have no idea how the imperial system works but I'm pretty sure if I ask you how much water you can pour into an 30x30x20 inches box and how much that water weights you'd most likely need a calculator?

We should have never adopted the pseudoinch (centimeter). Countries like The Netherlands and other western european countries were first to convert to metric and we needed something similar to the inch, so the centimeter was brought in (aka pseudoinch). Countries like Australia use mm almost exclusively, even carpenters, but they converted later and they adopted to the correct metric version. (version 2.0 if you will) Metric works best when stepping by the thousands. It takes the guesswork out of the conversion. If you are missing a decimal point it's easy to spot when using the jump from mm to meter, from milliliter to Liter, kilogram to gram, etc. We never use decigrams, but we do sometimes use deciliters or hectoliters (if you are a brewery). Especially the older generations use those in-between measurements more frequently. As for myself I was trained by a machinist and therefore mm and microns. But if I visit the hardware store and I asked for the MDF board to be cut up into 16 strips pieces of 66 the operator set it to 66 cm. How on earth he was going to cut 16 pieces from a 1200 wide board is beyond my reasoning, but thinking wasn't on his mind that day. So to this day I have to remind me that carpenters are usually trained to use centimeters (urgh)

CM is useful for quite a lot of situations but let me take your example here all you needed to do to make sure no confusion is to say MM or CM that is it. CM is also used far more commonly by normal (normal meaning not trained in specific things like a machinist) people. In your case you also called it a 1200 wide board while the "correct" way would be calling it 1.2 wide board as the unit of measure is Meter not the prefixes. Unlike the Gram where the Kilogram is the standard because of France, and a Gram is 1000s of a kilogram as a definition it is not that kilogram is 1000 grams (even though that is what it ends up being) as the prefix kilo indicates. So you are mad about a person not understanding that you are in a specialised work field that uses MM far more than the common man when you described it. However by context clues like you calling the board 1200 and not 120 or 1.2 the person should have known you spoke in mm. So while the person is in the wrong so are YOU Now there is also that people who work in a hardware store as clerks might have 0 training in the field you work in, but might be sellers a completely different degree. and if that is the case then CM is a far more commonly used term than mm for cutting things.

The metric system was developed around factors of 1000, mathmatically easier to spot mistakes to begin with. The centi, deci, deca hecta were added for convenience and allowing people to convert to the metric system, but it was not part of the original design. Why are there no subdivisions beyond mm? As for early adopters compared to late adopters the difference is quite noticeable. The late adopters are much more inclined to stick to the thousands. For example carpenters in australia use mm or meters, nothing in between. And it prevents mistakes, cut me a 1240 only means one thing. Cut me a 124, could me 1m24 or 124mm, quite the difference. As for the example i used more or less showed the problem with todays math/school system. It's simply not there. If you ask a board to be cut into 10 pieces, they logic should conclude that centimeters might not be the correct unit of measure. I am the customer, I should not be the one correcting the clerk. He should be the one assuming that the client could mean either.

But when you went and bought timber at the lumberyard, inch used for a long time until the mid 80's since then it has almost disappeared. Take a 2x4 in. It is 50.8 x 101.6 mm but today they are all rounded to 50 x 100 mm which makes it much easier to calculate the material consumption.

Because you said, that some wonder, why there is the difference in the folding rulers: in metric it is common to orientate on the general scale of your project to choose the prefix you refer to. Since folding rulers mostly are used in construction, a milimeter is often way too small as a unit, making the numbers to calculate with unnecessary long. That is why they often use centimeters and to make things more convenient the rulers are adapted to it. Also it is based on the accuracy you are probably going or want to achieve. That is why in roadworks you might find measurements in decimeters (10cm or 100mm) because a deviation of a few centimeters in the width of a two lane road are mostly not significant. But as you showed it is quite easy if you need to change to the next smaller or larger unit if it is necessary.

Most of the rulers and tape measures I've ever seen are in centimetres, so your millimetre ruler threw me for a bit. But it's pretty much like you said - it makes no difference. you grab the major units, then divide between them. 100 mm is 10 cm, every 10mm in there is 1 cm. Doesn't matter how you label the units, it's always the same units.

I think that bigger units like centimeters and meters are easier to understand once your use of metric system has become instinctive. Milimeters are somewhat too precise and, frankly speaking, not always needed for use in everyday life. To use an example in Imperial, I wouldn't say that "I'm 72 inches tall" if I can simply say "I'm 6ft tall" and everyone understands what I'm talking about. Metric system i far easier to use since operating in increments of 10 and changing units by adding or substracting zeros is far less complicated than conversions in Imperial. I believe some Americans during their transition to metric are getting stuck on the smallest unit of measurement in common use and they have a hard time adjusting to bigger ones.

This was formally stated 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 See also kzread.info/dash/bejne/kaCnyrR6gNm2irw.html and kzread.info/dash/bejne/Y5hnyaOTXbfLY7w.html

Some peoople really struggled with the change because they were always trying to convert fron one system to the other. The easy thing to do is to to get rules and measures in both systems, so when you need to work in inches you use a 12 inch rule, and if you need to work in mm , you use a 300mm rule. Then you don't need to do any converting in your head and inevitably get it wrong! As an example, I have 4 sets of drills.... one set of inch drills, one set of number drills, one set of letter drills and a set of metric drills, so when I need to drill a whole I use the set that suits what I need rather than trying to convert from one system to another and get it wrong.
