The length of an object is the distance between point A and point B. The basic length unit is the metre (m), using the The Metric System of Measurements of length. In geometric measurements, length is the most extended dimension of an object. In the International System of Quantities, length is any quantity with dimension distance. In other contexts, length is a measured dimension of an object. Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length. For example, it is possible to cut a length of wire shorter than the wire's width. In most systems of measurement, the unit of length is a base unit, from which other units are derived.
Here are multiples of the length:
1 nanometre = 1000 picometres
1 micrometre = 1000 nanometres
1 millimetre = 1000 micrometres
1 centimetre = 10 millimetres
1 decimetre = 10 centimetres
1 metre = 10 decimetres
1 decametre = 10 metres
1 hectometre = 10 decametres
1 kilometre = 10 hectometres |
