What's with the obsession of USians to measure thicknesses in ounces?
I can kind of understand measuring copper thickness of a PCB in oz/ft^2, as that is easier to measure than actual thickness in the µm range. Especially if you don't care about the thickness being even.
But who the f*** came up with the idea of measuring leather thickness in oz? What thickness is an 5oz leather? And does that change with each leather type or do you just pretend it's some ideal animal hide of known density?
The only measure more ridiculous than this, that I know of, is measuring nails in pence. Yes, the price that nails had somewhen in the 18th century is the way how nail thickness and length are measured. Today. In the 21th century.
Canadian friends, you use all kinds of units. Are you able to convert all of them or is the weight of a human a total different scale to you than a horse or a pack if flour? #units#imperialSystem#SIUnits
