I've been in the states now long enough to know what wonderful people you are, and I love you so much.
But there is something missing, and I hope this information can help you, and maybe someday be part of this great nation:
One milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat one degree Centigrade - which is one percent between freezing and boiling of water.
That's it, that's the metric system. It can solve a lot of confusion at work and at home. Just throwing it out there for anyone who wants to use it.
