Except WTF is the next size up or down from 15/64??!!!
There's lots of great reasons to switch to metric. Inability to do basic fractions isn't one of them...
For the record, it would be 16/64, or, 1/4
Nope! It'd be 6mm, then B gauge (6.045mm), then 1/4" (6.350mm). And that's not including things like over/under reamers and such.
(Sorry, I've been watching too much Blondihacks lately.)
Everyone has trouble with something that's basic for someone else - we just have different skills. If these fractions are too confusing for a significant minority of people, then that's a good reason to switch from fractional to decimal.
Except In this specific case, it's about measurements for tools. Fractional is far more practical for construction than decimal for tooling.
But somehow the brother is convinced, despite the fact that they left the hardware store without the bit they needed!
