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 128 grams into kilograms we have to multiply 128 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

128 g → M_(kg)

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

M_(kg) = 128 g × 0.001 kg

M_(kg) = 0.128 kg

The final result is:

128 g → 0.128 kg

We conclude that 128 grams is equivalent to 0.128 kilograms:

128 grams = 0.128 kilograms
