A barn (symbol: b) is a unit of area equal to 10−28 m2 (100 fm2). Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles.
| 1 barns = 2.0E-34 hides | 6 barns = 1.2E-33 hides |
| 2 barns = 4.0E-34 hides | 7 barns = 1.4E-33 hides |
| 3 barns = 6.0E-34 hides | 8 barns = 1.6E-33 hides |
