So how did you get your nickname used here?

I don't care which is better. But I think that having the old one when the whole word uses metric is an obstacle. Changing isn't much of a hassle. The only thing against changing I could think about is the nostalgy factor.

Think about the odd fractions you get when using the old imperial system. You are often dividing by 3 and other numbers which will multiply the number of decimals in the results. In a scientiphical environment, the less "carried error", the better, and the imperial system favourishes the carried error increase as we are doing more and more calculations.

It's not so difficult to change. It looks like it's difficult at first, but I guarantee you that in two years you'll know exactly how long is a kilometre or how heavy is a kilogram.

Having to change all the driving signs, for example... well, I don't think it's a very big problem. We had to change ALL our coins and paper money. And we survived :lol: And note that 1 euro = 166.3860 pesetas, so the conversion was tricky at times
