Sure, but diameter is also harder to measure on something like a latex tube. Just measure the circumference, divide by 2, then measure the condom.
I'd personally prefer it to be the circumference (so double the condom width).
Just divide that number by pi.
Then you can reasonably approximate with a ruler over the top with no math.
Why not divide by tau and then again by 2? Tau is superior anyway.
