But horrible at math.
like, I can look at certain things and guess it’s length within inches, and I know standard sizes of appliances, cabinet bases, and other household things.
i know that I can use a 13mm socket on a 1/2” head bolt. Same with a 14mm on a 9/16”, etc.
but god damn if I have to figure out a good estimate on how much money I’ll need for gas on a road trip I never can remember the formula and still need a calculator.
