To convert square feet to barns, multiply the value by 9.2903 × 10²⁶. To go the other way, multiply barns by 1.07639 × 10⁻²⁷ to get square feet.
| Square Feet (ft²) | Barns (b) |
|---|---|
| 1 ft² | 9.2903 × 10²⁶ b |
| 2 ft² | 1.85806 × 10²⁷ b |
| 5 ft² | 4.64515 × 10²⁷ b |
| 10 ft² | 9.2903 × 10²⁷ b |
| 20 ft² | 1.85806 × 10²⁸ b |
| 50 ft² | 4.64515 × 10²⁸ b |
| 100 ft² | 9.2903 × 10²⁸ b |
| 500 ft² | 4.64515 × 10²⁹ b |
| 1,000 ft² | 9.2903 × 10²⁹ b |
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.
Barn (b). A barn is 10⁻²⁸ m², the unit particle physicists use for nuclear cross-sections.
There are 9.2903 × 10²⁶ barns in one square foot.
Multiply the number of square feet by 9.2903 × 10²⁶. For example, 10 square feet equal 9.2903 × 10²⁷ barns.
One barn equals 1.07639 × 10⁻²⁷ square feet.
