Weight Converter

What is a Weight Converter?

A weight converter translates a measurement in one unit into all other supported units at the same time. Type any value and every other field updates instantly. Useful for cooking, shipping, fitness tracking, or any situation where weights are reported in an unfamiliar unit.

How It Works

All units convert through grams as the base:

1 milligram  = 0.001 g
1 ounce      = 28.35 g
1 pound      = 453.59 g
1 stone      = 6,350.3 g  (14 lb)
1 kilogram   = 1,000 g
1 metric ton = 1,000,000 g

Example

A person weighs 180 lb. In other units:

  • 180 lb x 453.59 = 81,647 g
  • = 81.65 kg
  • = 12 st 12 lb (12.857 stone)

Tips

  • A quick rule of thumb: 1 kg is about 2.2 pounds. Multiply kilograms by 2.2 for a rough pounds estimate.
  • 1 pound = 16 ounces. Useful for recipes when a scale shows ounces and your recipe lists pounds.
  • Stone is common in the UK for body weight. 1 stone = 14 pounds. 10 stone = 140 pounds = about 63.5 kg.
