Imperial units have a lot of advantages when you need to do accurate calculations and produce good measurements.
Since everything is fractions you don’t get irrational numbers and calculations are super easy even without calculators case and point say you need to square a measurement squaring 3/16th of an inch is something any fifth grader can do in their head or simply look it up in an easy table.
Squaring 4.7625mm on the other hand requires a calculator and since you get an irrational number you can’t easily accurately measure it with common tools in the real world.
- Aardwolf 8y agoWho says one has to use fractions with one unit and real numbers with another? Both units are just a different multiplier. What stops one from using 3/16th of a meter? (I admit I rarely see SI units with fractions, but if one finds them so useful, why not? Personally I prefer non-fractions by the way, it's much easier to rank and compare numbers in your head if they're all given as real numbers. E.g. can you tell quickly if 5/17 is bigger or smaller than 8/30?) And how will you square 2.829 inch? Not everything you measure will happen to be some perfect fraction
