How Weight Conversion Works
Weight and mass can be measured in many units. The most common are kilograms (kg), grams (g), milligrams (mg), metric tons (t), pounds (lb), ounces (oz), and stones (st). Each unit has a fixed relationship to the others.
- 1 kilogram (kg) = 1,000 grams (g) = 2.20462 pounds (lb)
- 1 pound (lb) = 16 ounces (oz) = 0.453592 kilograms (kg)
- 1 stone (st) = 14 pounds (lb)
- 1 metric ton (t) = 1,000 kilograms (kg)
Conversion Examples
1 pound = 16 ounces
Example: Convert 5 kilograms to pounds and ounces
5 kilograms × 35.27396 = 176.37 ounces
