Kilogram Converters

Convert kilograms to pounds, ounces, grams, stones, tons and other mass units, and back again.

What this tool does

Convert kilograms to pounds, ounces, grams, stones, tons and other mass units, and back again. Type an amount in kilograms, choose the units, and the tool converts it to grams. It offers 12 mass units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 12 options, including Kilogram, Gram, Milligram, Microgram, Tonne (metric ton), Pound (avoirdupois). Starts as Kilogram.
  • To: Choose one of the same 12 units as "From". Starts as Gram.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from kilograms to grams:

  • 1 kg = 1,000 g
  • 5 kg = 5,000 g
  • 10 kg = 10,000 g
  • 50 kg = 50,000 g
  • 100 kg = 100,000 g

Multiply the number of kilograms by 1,000 to get grams. Both units are exact definitions, so 1,000 is the exact factor: 1 kg = 1,000 g.

Limitations

  • Converts mass units only. It does not convert between mass and volume or energy, which needs a density or other second value.
