Measurement systems are tools. I have no problem using what I need to use. I don’t see any need to try to convert a culture.
The metric system has its merits in some cases. In others, not. Celsius is a horrible system. Degrees are too large (you have to use one decimal point for any precision) and the scale is about useless for human activity. (0-100 F is the “normal” range of human existence, much more everyday practical than the boiling/freezing points of water.)
The metric system is not natural. It tries to make up for lack of naturalness with ease of conversion. It’s a hard sell.
People have cups of milk and pints of beer. There are inches and feet and yards to measure different scales of things. There is no metric commonly-used measure between centimeters and meters. Beverages have to be measured in hundreds of milliliters or tens of centimeters.
In Canada they have “metric gallons” of milk (4 liters) for sale. Why? Because a gallon is a practical size for a family. It just doesn’t conveniently fit on a “multiple of ten” boundary.
Give up a connection to the English language and a naturally-evolved system so a Frenchman only has to divide by ten? That’s not very conservative.
yes, I have always thought it was BS.
