I agree that metric system is much easier.
The relationship between cm->m->km is very logical. C temp, liters, kilos. they all connect with each other so effortlessly in all the calculations.
But relationship between ft -> yard ->mile eludes me to this day. as are oz, quarts, gallons. I cannot understand why would anyone willingly choose to live by the system that is so illogical and inconvenient.
So I'm thinking of getting a metric computer (even though all the diving I learned was in the imperial system) but I plan to be diving in Europe in Asia, so maybe it is not a bad idea.
I hope I will adjust easily. I just would like to know if there is anything I did not anticipate?
(btw, the computer is air integrated (nitrox too))
