1 kg = 1000 g
To convert 21 kilograms into grams we have to multiply 21 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 kg → M(g)
Solve the above proportion to obtain the mass M in grams:
M(g) = 21 kg × 1000 g
M(g) = 21000 g
The final result is:
21 kg → 21000 g
We conclude that 21 kilograms is equivalent to 21000 grams:
21 kilograms = 21000 grams
