1,0 m. That is so for most people of moderate size. That is very easy for measuring a length of rope. Pick it up in your left hand, strech to your right shoulder, and there is your meter. But that does not prove superiority. By the same token I could have stretched the rope on the floor and measured 3 footpasses plus something. The superiority is in the simple and uniform way of measuring and expressing these measurements. In decimal, not in fractions. The primitive fractions 1/2, 1/4 may be easy. But if you come to 5/32" is is more difficult. I met 15/64" .. it takes a handheld japanese to get even an idea of what is ment.
We are modelbuilders. Mostly we deal with plans in inches and feet, yes even in Europe because we model ancient prototype, and the plans of that are in inches too. Gently this will change. Our grandchildren have to be educated in converting those vintage units. Only if they model.
