What units are used to measure lengths?

Objects can be measured in kilometres (km), metres (m), decimetres (dm), centimetres (cm), or millimetres (mm).

Observe the length of what needs to be measured to choose which unit of measurement to use. Generally, longer distances require larger units of measurement.

Example

The distance between two cities is measured in kilometres.
The width of a classroom is measured in metres.
The height of a desk is measured in decimetres.
The length of a pencil is measured in centimetres.
The thickness of a book is measured in millimetres.
The depth of a swimming pool is measured in metres.

Units of measurement can be converted from one form to the other using certain equivalent relationships.

Example

1 km = 1 000 m = 10 000 dm = 100 000 cm = 1 000 000 mm
