To convert square centimeters to barns, multiply the value by 1 × 10²⁴. To go the other way, multiply barns by 1 × 10⁻²⁴ to get square centimeters.
| Square Centimeters (cm²) | Barns (b) |
|---|---|
| 1 cm² | 1 × 10²⁴ b |
| 2 cm² | 2 × 10²⁴ b |
| 5 cm² | 5 × 10²⁴ b |
| 10 cm² | 1 × 10²⁵ b |
| 20 cm² | 2 × 10²⁵ b |
| 50 cm² | 5 × 10²⁵ b |
| 100 cm² | 1 × 10²⁶ b |
| 500 cm² | 5 × 10²⁶ b |
| 1,000 cm² | 1 × 10²⁷ b |
Square centimeter (cm²). A square centimeter is the area of a square with 1 cm sides, widely used in schools and for small surfaces.
Barn (b). A barn is 10⁻²⁸ m², the unit particle physicists use for nuclear cross-sections.
There are 1 × 10²⁴ barns in one square centimeter.
Multiply the number of square centimeters by 1 × 10²⁴. For example, 10 square centimeters equal 1 × 10²⁵ barns.
One barn equals 1 × 10⁻²⁴ square centimeters.
