Barn (b). A barn is 10⁻²⁸ m², the unit particle physicists use for nuclear cross-sections.
Square meter (m²). The square meter is the SI unit of area, the area of a square with 1 m sides.
There are 1 × 10⁻²⁸ square meters in one barn.
Multiply the number of barns by 1 × 10⁻²⁸. For example, 10 barns equal 1 × 10⁻²⁷ square meters.
One square meter equals 1 × 10²⁸ barns.
