About this conversion

This Koverts page converts avoirdupois pounds (lb) to kilograms (kg) for body weight, food, and shipping — using the standard mass conversion, not pound-force.

The pound (lb) is an imperial unit of mass used in the United States and United Kingdom. One pound equals 16 ounces and is commonly used for body weight and food portions.

The kilogram (kg) is the base unit of mass in the metric system. It is the most widely used unit for body weight and food measurement outside the US.

Typical uses

  • Body weight conversion for international travel
  • Food and recipe ingredient conversions
  • Gym and fitness equipment weight settings
  • Shipping and postal weight limits
