To convert 21.7 grams into kilograms we have to multiply 21.7 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

21.7 g → M(kg)

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

M(kg) = 21.7 g × 0.001 kg

M(kg) = 0.0217 kg

The final result is:

21.7 g → 0.0217 kg

We conclude that 21.7 grams is equivalent to 0.0217 kilograms:

21.7 grams = 0.0217 kilograms
