Why kg to lbs is a multiplication by 2.20462
The pound is defined as exactly 0.45359237 kilograms, agreed internationally in 1959. Invert that and you get 2.20462 pounds per kilogram. It is a definition rather than a measurement, so the factor never drifts. For a quick mental estimate, double the kilograms and add ten percent, which puts 70 kg at roughly 154 lbs. The exact figure is 154.32.
lbs to kg for gym plates and luggage
Converting lbs to kg means dividing by 2.20462, or multiplying by 0.4536 if you prefer. This is the everyday direction for anyone reading American gym equipment or an airline allowance written in pounds. A 45 lb barbell plate is 20.41 kg, and a 50 lb baggage limit is 22.68 kg, which is why a 23 kg allowance is not quite the same thing.
lbs to oz and oz to g in the kitchen
Recipes are where the small units bite. There are exactly 16 ounces in a pound, so lbs to oz is a simple multiplication. Going metric, one ounce is 28.3495 grams, so oz to g means multiplying by roughly 28.35. American recipes tend to use ounces by weight for dry goods and fluid ounces for liquids, and the two are not interchangeable, so check which one the recipe means before converting.
stone to lbs and body weight
The stone is still normal in Britain and Ireland for body weight and almost nowhere else. One stone is exactly 14 pounds, so stone to lbs is a multiplication by 14, and 11 stone 4 is 158 lbs or 71.67 kg. The converter above handles stones directly, so you do not have to work through pounds first.
