Decare / Barn Units Definition
Decare
The decare or dekare (/ˈdɛkɑːr, -ɛər/) is derived from deca and are, and is equal to 10 ares or 1000 square meters. It is used in Norway and the former Ottoman regions of the Middle East and the Balkans (Bulgaria) as a measure of land area.
Barn
A barn (symbol: b) is a metric unit of area equal to 10-28 m2 (100 fm2). Originally used in nuclear physics to express the cross section of nuclei and nuclear reactions, it is also used today in all areas of high energy physics to express the cross sections of any diffusion process, and is best understood as a measure of the probability of interaction between small particles. A barn corresponds approximately to the cross section of a uranium nucleus. The barn is also the unit of area used in nuclear quadrupole resonance and nuclear magnetic resonance to quantify the interaction of a nucleus with an electric field gradient. Although the barn was never an SI unit, the SI standards body recognized it in the 8th SI brochure (replaced 2019) due to its use in particle physics.
