Kilograms to grams

1 kilogram = 1,000 grams

Type a value in kilograms (kg) to get grams (g) straight away. A kilogram is larger than a gram, so the number goes up. Both units belong to weight, measured here against the kilogram.

1 kg = 1,000 g

Formula

g = kg × 1,000

One kilogram is 1,000 grams, so multiply the kilogram value by that factor. Here kg is the value in kilograms and g is the result in grams.

Worked example: 70 kilograms × 1,000 = 70,000 grams.
