Quick Rough Maths

To get the Barns, multiply the number of Square Metres by 1.0E+16 trillion

Square Metres (m²) in 1 barn

There are 0 Square Metres in 1 barn

Barns (b) in 1 Square Metre

There are 1.0E+28 Barns in 1 Square Metre

Symbol: **m²**

Unit System: SI

Unit System: SI

The square metre is a unit of area and is an SI derived unit with the symbol m².

It was introduced in 1954 when the International System of Units was established and was derived directly from one of the original 6 base units - the metre (m).

It can be prefixed with any of the SI symbols that multiply it up or down such as km² (square kilometre) or µm2 (square micrometre). It is the most commonly used unit of area and is recognised all over the world.

Symbol: **b**

Unit System: Particle Physics

The barn is a unit of area and is used in particle physics with the symbol b.

It represents approximately the area of the cross-section of a uraneum nucleus, so is very small compared to most other recognised units of area.

It is also used to measure the interaction of a nucleus with an electric field gradient in nuclear quadrupole and magnetic resonance.
