To convert square inches to barns, multiply the value by 6.4516 × 10²⁴. To go the other way, multiply barns by 1.55 × 10⁻²⁵ to get square inches.
| Square Inches (in²) | Barns (b) |
|---|---|
| 1 in² | 6.4516 × 10²⁴ b |
| 2 in² | 1.29032 × 10²⁵ b |
| 5 in² | 3.2258 × 10²⁵ b |
| 10 in² | 6.4516 × 10²⁵ b |
| 20 in² | 1.29032 × 10²⁶ b |
| 50 in² | 3.2258 × 10²⁶ b |
| 100 in² | 6.4516 × 10²⁶ b |
| 500 in² | 3.2258 × 10²⁷ b |
| 1,000 in² | 6.4516 × 10²⁷ b |
Square inch (in²). A square inch is the area of a square with 1-inch sides (6.4516 cm²).
Barn (b). A barn is 10⁻²⁸ m², the unit particle physicists use for nuclear cross-sections.
There are 6.4516 × 10²⁴ barns in one square inch.
Multiply the number of square inches by 6.4516 × 10²⁴. For example, 10 square inches equal 6.4516 × 10²⁵ barns.
One barn equals 1.55 × 10⁻²⁵ square inches.
