Conversion formula

The conversion factor from kilograms to grams is 1000, which means that 1 kilogram is equal to 1000 grams:

1 kg = 1000 g

To convert 21.1 kilograms into grams we have to multiply 21.1 by the conversion factor in order to get the mass amount from kilograms to grams. We can also form a simple proportion to calculate the result:

1 kg → 1000 g

21.1 kg → M_(g)

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

M_(g) = 21.1 kg × 1000 g

M_(g) = 21100 g

The final result is:

21.1 kg → 21100 g

We conclude that 21.1 kilograms is equivalent to 21100 grams:

21.1 kilograms = 21100 grams
