The name micri-erg was proposed in 1922 by William Draper Harkins as a unit of energy equating to 10 − 14 erg,, as a convenient unit for the surface energy of molecules in surface chemistry.
The name micri-erg was proposed in 1922 by William Draper Harkins as a unit of energy equating to 10 − 14 erg, the equivalent to 10 − 21 joule. This was proposed as a way to measure the surface energy of molecules in surface chemistry.
