To convert 31 grams into kilograms we have to multiply 31 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

31 g → M(kg)

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

M(kg) = 31 g × 0.001 kg

M(kg) = 0.031 kg

The final result is:

31 g → 0.031 kg

We conclude that 31 grams is equivalent to 0.031 kilograms:

31 grams = 0.031 kilograms
