Convert mass and capacity units
1 kilogram = 1000 grams and 1 litre = 1000 millilitres. To change the small unit into the big unit, divide by 1000, because you need fewer of the bigger unit. To change the big unit into the small one, multiply by 1000. For a mixed amount like 2 kg 50 g, change the kilograms first (2000 g) and then add: 2050 g. As a decimal, 2050 g is 2.05 kg: the zero holds the tenths place.
