Some reference points to help you understand metric and imperial weights:
1 kilogram equals 2.20462 pounds. This is the exact international conversion factor, defined by the kilogram's relationship to the pound.
1 ounce equals 28.3495 grams. Since 1 pound = 453.592 grams and 1 pound = 16 ounces, one ounce = 453.592 ÷ 16 = 28.3495 grams.
The stone is primarily used in the United Kingdom for measuring body weight. 1 stone = 14 pounds. It's rarely used outside the UK, but common in UK healthcare and fitness contexts.
Simply multiply your weight in kilograms by 2.20462 to get pounds. For example, 70 kg × 2.20462 = 154.32 pounds.
