How to use the weight converter
- 1 Type the value you want to convert.
- 2 Choose the unit you are converting from, such as kilograms.
- 3 Choose the unit you want to see, such as pounds; the answer appears at once.
- 4 Check the table for the same weight in every other unit, or press swap to reverse.
Weights that often cause confusion
- Pound: exactly 0.45359237 kg, so 1 kg is about 2.2046 lb.
- Stone: used for body weight in the UK and Ireland; 1 stone is 14 lb, about 6.35 kg.
- Tons: a metric tonne is 1,000 kg, a UK long ton 1,016 kg and a US short ton 907 kg.
- Gold: a tola is 11.6638 g, and gold prices quoted per troy ounce use 31.1035 g, not the 28.35 g ounce used for food.
- Cooking: cups measure volume, not weight, so a cup of flour weighs much less than a cup of sugar.
