Tips and common mistakes
The pound is defined as exactly 0.45359237 kg, and the avoirdupois ounce as one sixteenth of a pound (28.349523125 g). A stone is 14 pounds, which is 6.35029318 kg. These are the units used for body weight in the UK and for most food and shop weights.
Watch out for the troy ounce, used for gold and silver, which is about 31.1 g and is not the same as the everyday ounce. Also check whether a figure is in pounds or stones, because 11 st is 154 lb, not 11 lb.
For a rough mental conversion, a kilogram is about 2.2 lb, and 100 g is a little over 3.5 oz.
