Formula

pm = km x 1.0E+15

Quick Rough Maths

To get the Picometres, multiply the number of Kilometres by 1000 trillion

Kilometres (km) in 1 Picometre

There are 0 Kilometres in 1 Picometre

Picometres (pm) in 1 Kilometre

There are 1.0E+15 Picometres in 1 Kilometre

Symbol: **km**

Unit System: SI

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.

The picometre is a unit of length and is a multiple of the SI unit metre. It uses the symbol pm.

It represents one trillionth of a metre, or one hundredth of an Ångström.

Because the picometre is so small, its use is restricted almost entirely to chemistry, quantum physics and particle physics. Atoms are typically 62 pm and 520 pm.

LISA (Laser Interferometer Space Antenna) is a probe planned for launch in 2034 to detect gravitational waves in space. Its measures these displacements with an accuracy of up to 20 pm over a distance of 2,500,000,000 m.
