## 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 2.1 grams into kilograms we have to multiply 2.1 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

2.1 g → M(kg)

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

M(kg) = 2.1 g × 0.001 kg

M(kg) = 0.0021 kg

The final result is:

2.1 g → 0.0021 kg

We conclude that 2.1 grams is equivalent to 0.0021 kilograms:

2.1 grams = 0.0021 kilograms ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 476.19047619048 × 2.1 grams.

Another way is saying that 2.1 grams is equal to 1 ÷ 476.19047619048 kilograms.

## Approximate result

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

2.1 g ≅ 0.002 kg

An alternative is also that one kilogram is approximately four hundred seventy-six point one nine times two point one grams.
