I have one personal example where the inches, pounds, centimeters and stones don't matter - the archery community. "This bow was measured to produce 50 pounds of force at 28" draw length." Nobody argues about it, or takes it personally or tries convert to joules. It's a convention. Everyone uses it, from English Long Bow makers to the Koreans and the Chinese, et al. Similar with the firearms, American enthusiast don't insist on converting 9mm Luger to 0.354" and many of us know what Kurtz means.

I'll die on the Fahrenheit hill though. A 100F is 100% torture. 70% (70F) is tolerable. 35.3C tells me nothing on a scale.
