Americans: I use miles and pounds
Europeans: I use kilometres and kilograms
Canadians: [snorting a line of assorted measuring systems] I'm 5'3, I weigh 150 lbs, horses weigh 1000 kgs, my house is an hour away and I drive 80 km/h to get there, I need a cup of flour and 1L of milk.
Linda: My stove is in Fahrenheit and my recipes are in Celsius! I spend a lot of time converting recipes and sometimes they don't turn out!
