There’s a few aspects of the metric system that even Canadians can’t get into our heads. For instance, for a person’s height and weight, we still work in pounds and feet/inches, and for recipes, we still use cups and teaspoons, for some unfathomable reason. Despite measuring everything in the scientific field using metric, all distances except for our own height in meters/kilometers, and all volumes of liquid and solid matter in liters which correspond to cubic meters (1 milliliter = 1 cubic centimeter), we still have problems with the human measurements for some reason. I’m not immune — in my last post I did exactly that, saying I weigh 180lbs. But here in Canada, I actually weigh 81.64kg! Those of you looking to lose weight should move up here post-haste.

Such as:
