Unit Information

Symbol: km
Unit System: SI

What is the Kilometre?

The kilometre is a unit of length and is a multiple of the metre; an SI derived unit. It has the symbol km.

A kilometre is equal to 1000m, 1094 yards and 0.621 miles.

Kilometres is used to measure road distances in the US, though the UK is still using the imperial "sister" miles.

Symbol: nm
Unit System: SI

What is the Nanometre?

The nanometre is a unit of length and is a multiple of the SI unit metre. It uses the symbol nm.

1 nm is equal to one one-billionth of a metre. (Nano is the prefix for one billionth). It is used to express dimensions on an atomic scale for example a helium atom has a radius of approximately 0.03nm.

The nanometre was previously known as the millimicrometre (or the millimicron).
