## 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 20 grams into kilograms we have to multiply 20 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

20 g → M(kg)

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

M(kg) = 20 g × 0.001 kg

M(kg) = 0.02 kg

The final result is:

20 g → 0.02 kg

We conclude that 20 grams is equivalent to 0.02 kilograms:

20 grams = 0.02 kilograms ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 50 × 20 grams.

Another way is saying that 20 grams is equal to 1 ÷ 50 kilograms.

## Approximate result

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

20 g ≅ 0.02 kg

An alternative is also that one kilogram is approximately fifty times twenty grams.
