Units within the same family are linked by simple conversions:

1 cm=10 mm,1 m=100 cm,1 km=1 000 m,1\text{ cm} = 10\text{ mm}, \quad 1\text{ m} = 100\text{ cm}, \quad 1\text{ km} = 1\,000\text{ m},
1 kg=1 000 g,1 l=1 000 ml.1\text{ kg} = 1\,000\text{ g}, \quad 1\text{ l} = 1\,000\text{ ml}.

To change a bigger unit into a smaller one, multiply. To change a smaller unit into a bigger one, divide.
