## 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 15 grams into kilograms we have to multiply 15 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

15 g → M(kg)

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

M(kg) = 15 g × 0.001 kg

M(kg) = 0.015 kg

The final result is:

15 g → 0.015 kg

We conclude that 15 grams is equivalent to 0.015 kilograms:

15 grams = 0.015 kilograms

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 66.666666666667 × 15 grams.
