kg = g × 0.001

Converter

Input

Result

0.001kg

kg = g × 0.001

g = kg × 1,000

Example: 10 g = 10 × 0.001 = 0.01 kg.

Express both g and kg in the same base unit kg (kilogram), then cancel the shared base unit.

1
Rewrite g in the base unit
$1 g = 0.001 kg$
2
Rewrite kg in the base unit
$1 kg = 1 kg$
3
Forward conversion
$1 g = \frac{0.001 kg}{1 kg} \times 1 kg = \frac{0.001}{1} kg = 0.001 kg$
4
Reverse conversion
$1 kg = \frac{1 kg}{0.001 kg} \times 1 g = \frac{1}{0.001} g = 1, 000 g$

This conversion expresses mass in grams in terms of kilograms. The factor 0.001 directly relates the two SI units.

The kilogram (kg) is the base SI unit of mass. The gram (g) is a derived unit equal to one thousandth of a kilogram.

The conversion factor holds because both units are defined within the same metric system. One gram is defined as 0.001 kilograms.

The conversion uses the exact definitions of the gram and the kilogram within the International System of Units (SI).

1 g = 0.001 kg.

10 g = 0.01 kg.

100 g = 0.1 kg.

Use kg = g × 0.001.

1 kg = 1,000 g.

Use the conversion factor and round the result to the precision required by your calculation.
