This constant represents the ratio of the mass of a muon to the mass of an electron.
A muon is an elementary particle classified as a lepton which has properties similar to an electron: it has spin of -1/2 and charge of -1. The muon however has significantly more mass than an electron.
This constant is specified with a standard uncertainty (standard deviation) of: 0.000 0052
