How do you convert 120 grams into kilograms?

Answer 1

You use the conversion factor of 1 kilogram is equal to 1000 grams:

1 kg = 1000 g

You then multiply your current value so that all the units you are trying to get rid of (in this case grams) cancels out and you are left with the units you want (kilograms in this case).

(120 g) * (1 kg / 1000 g) = (120/1000) = 0.12 kg

Answer 2

12 kg = 12 000 g

To convert from kg to g, you multiply the given value by 1000.
