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 1003 grams into kilograms we have to multiply 1003 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

1003 g → M_(kg)

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

M_(kg) = 1003 g × 0.001 kg

M_(kg) = 1.003 kg

The final result is:

1003 g → 1.003 kg

We conclude that 1003 grams is equivalent to 1.003 kilograms:

1003 grams = 1.003 kilograms
