Metric Units and Measurement<br />
Metric Units and Measurement 1<br />
Length<br />
The standard unit of length in the metric system is the metre. Other units of<br />
length and their equivalents in metres are as follows:<br />
1 millimetre = 0.001 metre<br />
1 centimetre= 0.01 metre<br />
1 decimetre = 0.1 metre<br />
1 kilometre = 1000 metres<br />
100 centimetres = 1 metre<br />
1000 millimetres = 1 metre<br />
We symbolize these lengths as follows:<br />
1 millimetre = 1 mm<br />
1 centimetre = 1 cm<br />
1 metre = 1 m<br />
1 decimetre = 1 dm<br />
1 kilometre = 1 km<br />
For reference, 1 metre is a little longer than 1 yard or 3 feet. It is about half the<br />
height of a very tall adult. A centimetre is nearly the diameter of a dime, a little<br />
less than half an inch. A millimetre is about the thickness of a dime.<br />
Volume<br />
The standard unit of volume in the metric system is the litre. One litre is equal to<br />
1000 cubic centimetres in volume. Other units of volume and their equivalents in<br />
litres are as follows:<br />
1 millilitre = 0.001 litre<br />
1 centilitre = 0.01 litre<br />
1 decilitre = 0.1 litre<br />
1 kilolitre = 1000 litres<br />
We symbolize these volumes as<br />
follows:<br />
1 millilitre = 1 ml<br />
1 centilitre = 1 cl<br />
