The debye (symbol: D) is a non-SI, CGS unit of electrical dipole moment. It is defined as 1 statcoulomb centimeter (or 1 esu m, or 1 Fr cm). In SI units, 1 D equals approximately 3.33564 coulomb-meter (exactly 1 C m2/s divided by c, the speed of light in vacuum). Conversely 1 C m = 2.9979 D.It is named after the physicist Peter J. W. Debye. Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10-10 statcoulomb (generally ca… (More on Debye)
