People are still citing the base 10 advantage despite my proof that you could still apply it to the imperial system and get the exact same advantage. On top of that you have more choices of what units to use because they aren't equivalent.
This the most cited reason for using the metric system is using the base 10 formula. Kilometer is 1000 meters, a kilogram is 1000 grams ect. But everyone seems to fail to realize that you can do the same thing with the imperial system.
Take the kilopound, it's 1000 pounds, a cenipound could be 1/100 of a pound. You've just taken the base 10 advantage of the metric system and applied it to the imperial system with little to no reducation of training.
Also the reason why the conversions of imperial are always 3 feet = yard, 12 inches = 1 feet is because base 3, 4 numbers have more factors than base 10.
Numbers that can divide by base 10
- 1, 2 ,5, 10
Numbers that can divide by base 12 (12 inches = foot)
- 1,2,3, 4, 6, 12
Numbers that can divide by base 16 (16 Ounces = 1 Pound)
- 1, 2, 4, 8, 12
As a result you can divide 12 by 3 or 4 without ending up with decimals or reconverting the whole unit system. This is why it has been used for centuries because it was easier to deal with in everyday life without ending up in tedious decimal places.
I think you are completely misunderstanding why people say the base 10 is better for metric. It's not because you can arbitrarily divide the units up by ten - it's because you can rely on the fact that the units are measured in tens. Like, if I am using inches, feet and yards I need to know there are 12 inches in a foot, but there are 3 foot in a yard. That system is so arbitrary its hard to put into words. With the metric system I know exactly how many units are in the next unit up (1000mm is a metre, 1000m is a kilometre.)
This. I find it hard to comprehend how someone would scale a drawing or map using imperial units. With metric, you have a simple way to read the distances involved.
