## 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 3 grams into kilograms we have to multiply 3 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

3 g → M(kg)

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

M(kg) = 3 g × 0.001 kg

M(kg) = 0.003 kg

The final result is:

3 g → 0.003 kg

We conclude that 3 grams is equivalent to 0.003 kilograms:

3 grams = 0.003 kilograms

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 333.33333333333 × 3 grams.

Another way is saying that 3 grams is equal to 1 ÷ 333.33333333333 kilograms.

## Approximate result

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

3 g ≅ 0.003 kg

An alternative is also that one kilogram is approximately three hundred thirty-three point three three three times three grams.
