Common pitfalls and look-alike units

The "Calorie" on food labels and in fitness is the kilocalorie (kcal): 1 kcal = 4184 J, and the small calorie (cal) is one thousandth of it. This page uses the thermochemical calorie (1 cal = 4.184 J); the International Steam Table calorie is about 4.1868 J, so values differ slightly. The "degree" (度) on a Chinese electricity bill is one kilowatt-hour, and 1 kWh = 3600 kJ.
