Convert Metric Measurements From One Unit to Another

We know that kilo means 1,000.

We also need to know that centi means a hundredth and milli means a thousandth.

1 centimetre is 1/100 of a metre and 1 centilitre is 1/100 of a litre.

1 millimetre is 1/1000 of a metre and 1 millilitre is 1/1000 of a litre.

So 10 mm = 1 cm

10 ml = 1 cl

1 kg = 1,000 g

Example

Convert 24.5 cl to ml and l.

10 ml = 1 cl, so we multiply 24.5 by 10 to get 245 ml.

245/1000 = 0.245 litres

Answer: 24.5 cl = 245 ml and 0.245 l
