Hi, I think in metric units, so almost everything is some form of a power of 10, like a kilogram is a 1000 grams, etc.
Sometimes I will think of an hour and half as 150 minutes before remembering that it is 90 minutes.
Does something similar happen to imperial units users? Because as far as I understand you don’t have obvious patterns that would cause you to make these mistakes, right?
I think in both imperial and metric, imperial forces more fractions into my thought, which may be useful for time divisions. Fractions can definitely be quicker for centering things along a length. But when I’m designing for 3d printing (a fertile that has always been metric based) I prefer mm/cm.
