Micri-

micri is an archaic non-SI decimal metric prefix for 10−14. Its symbol was mc.[1]

The name micri-erg was proposed in 1922 by William Draper Harkins as a unit of energy equating to 10−14 erg,[2][3][4][5][6] the equivalent to 10−21 joule. This was proposed as a way to measure the surface energy of molecules[5] in surface chemistry.[7]
