FAQ
Frequently Asked Questions
A millibarn is a unit of area equal to 10^-31 square metres, used in physics to express the cross-sectional area of atomic nuclei and particles during interactions.
No, it is a highly specialized term with no application in general English. Its use would be confusing outside of specific scientific contexts.
During the Manhattan Project, physicists humorously referred to the large (for nuclear physics) cross-section of 10^-28 m² as 'as big as a barn'. 'Millibarn' is a fractional subunit of this.
In British English, pronounce it as /ˈmɪl.ɪ.bɑːn/ (MIL-i-bahn). In American English, it's /ˈmɪl.ə.bɑːrn/ (MIL-uh-barn).
A unit of cross-sectional area in nuclear physics, equal to one thousandth of a barn.
Millibarn is usually technical/scientific in register.
