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?
You’re still thinking of a pattern – but there is a conflation between cardinal numbers and proportion/percentage. An hour and a half is 150% of one hour.
But no, that doesn’t happen with imperial systems, because there just aren’t really patterns to that level.
