Unit Information

Picometre
/pē′kə-mē′tər/
Symbol: pm
Unit System: SI

What is the Picometre?

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.

Ell
/ɛl/
Symbol: ell
Unit System: Historic English

What is the Ell?

The ell is a unit of length and originates from historic England and uses the symbol ell.

The ell usually measured 45in or 1.143m but was origally a "cubit" - which was the length from your elbow to the tip of your fingers and literally translated from the word "arm". It was mostly used in the tailoring world when buying and selling textiles.

Although now obsolete, the word "ell" still survives in the English word "elbow".
