Pounds to Kilograms

To convert pounds to kilograms, multiply by 0.453592 — or simply divide by 2.2 for a quick estimate. For example, 150 lbs is about 68 kg and a 45 lb barbell plate is 20.4 kg.

The kilogram is the international standard of mass, while the pound persists in the United States and, informally, in the United Kingdom. Use this tool for body weight, cooking and shipping conversions. The reverse converter turns kilograms into pounds.
