## Conversion formula

The conversion factor from grams to kilograms is 0.001, which means that 1 gram is equal to 0.001 kilograms:

1 g = 0.001 kg

To convert 21.1 grams into kilograms we have to multiply 21.1 by the conversion factor in order to get the mass amount from grams to kilograms. We can also form a simple proportion to calculate the result:

1 g → 0.001 kg

21.1 g → M(kg)

Solve the above proportion to obtain the mass M in kilograms:

M(kg) = 21.1 g × 0.001 kg

M(kg) = 0.0211 kg

The final result is:

21.1 g → 0.0211 kg

We conclude that 21.1 grams is equivalent to 0.0211 kilograms:

21.1 grams = 0.0211 kilograms

## Alternative conversion

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point one grams is approximately zero point zero two one kilograms:

21.1 g ≅ 0.021 kg

An alternative is also that one kilogram is approximately forty-seven point three nine three times twenty-one point one grams.
