To convert barns to square feet, multiply the value by 1.07639 × 10⁻²⁷. To go the other way, multiply square feet by 9.2903 × 10²⁶ to get barns.
| Barns (b) | Square Feet (ft²) |
|---|---|
| 1 b | 1.07639 × 10⁻²⁷ ft² |
| 2 b | 2.15278 × 10⁻²⁷ ft² |
| 5 b | 5.38196 × 10⁻²⁷ ft² |
| 10 b | 1.07639 × 10⁻²⁶ ft² |
| 20 b | 2.15278 × 10⁻²⁶ ft² |
| 50 b | 5.38196 × 10⁻²⁶ ft² |
| 100 b | 1.07639 × 10⁻²⁵ ft² |
| 500 b | 5.38196 × 10⁻²⁵ ft² |
| 1,000 b | 1.07639 × 10⁻²⁴ ft² |
Barn (b). A barn is 10⁻²⁸ m², the unit particle physicists use for nuclear cross-sections.
Square foot (ft²). A square foot is 0.09290304 m², the standard unit for building and floor areas in the US, UK, India and many other countries.
There are 1.07639 × 10⁻²⁷ square feet in one barn.
Multiply the number of barns by 1.07639 × 10⁻²⁷. For example, 10 barns equal 1.07639 × 10⁻²⁶ square feet.
One square foot equals 9.2903 × 10²⁶ barns.
