Formula

b = ha x 1.0E+32

Quick Rough Maths

To get the Barns, multiply the number of Hectares by 1.0E+20 trillion

Hectares (ha) in 1 barn

There are 0 Hectares in 1 barn

Barns (b) in 1 Hectare

There are 1.0E+32 Barns in 1 Hectare

Symbol: **ha**

Unit System: Non-SI Metric

Unit System: Non-SI Metric

The hectare is a unit of area and is a non-SI but metric unit with the symbol ha.

It represents the area equal to that of a square with edges 100m long (ie 1hm² or 10,000m²). This is the equivalent to about 2.47 acres.

Its size is down to its use primary use; that for measuring the size of land.

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.
