## 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 4.5 grams into kilograms we have to multiply 4.5 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

4.5 g → M(kg)

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

M(kg) = 4.5 g × 0.001 kg

M(kg) = 0.0045 kg

The final result is:

4.5 g → 0.0045 kg

We conclude that 4.5 grams is equivalent to 0.0045 kilograms:

4.5 grams = 0.0045 kilograms

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 222.22222222222 × 4.5 grams.

Another way is saying that 4.5 grams is equal to 1 ÷ 222.22222222222 kilograms.

## Approximate result

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

4.5 g ≅ 0.005 kg

An alternative is also that one kilogram is approximately two hundred twenty-two point two two two times four point five grams.
