Pounds to kilograms
kilograms = pounds × 0.45359237
Example: 150 lb = 150 × 0.45359237 = 68.04 kg
Grams to ounces
ounces = grams × 0.0352739619

Frequently asked questions
How do I convert kilograms to pounds?
Multiply the kilogram value by 2.2046. For example, 70 kg = 70 × 2.2046 = 154.3 lbs. To convert pounds to kilograms, multiply by 0.4536. A quick mental estimate: multiply kg by 2.2 for a close approximation — 80 kg ≈ 176 lbs.
How many pounds are in a kilogram?
One kilogram equals approximately 2.2046 pounds. One pound equals exactly 0.45359237 kilograms. This conversion is most commonly needed for body weight (US uses pounds, most of the world uses kilograms) and for food and ingredient quantities in imported recipes.
How do I convert pounds to stones?
Divide the pound value by 14. For example, 154 lbs ÷ 14 = 11 stone. To get stones and pounds, take the whole number of stones and the remainder is the pounds. For example, 160 lbs = 11 stone 6 lbs (11 × 14 = 154, 160 − 154 = 6). The stone unit is used almost exclusively in the UK and Ireland for body weight.
