Charge-to-mass ratio

The charge-to-mass ratio of an electron is commonly used for charged particles in physics and chemistry. It can be calculated experimentally or theoretically, and is simply equal to the fundamental elementary charge, e=1.6022\times 10^{-19} C, divided by the electron's mass, m_{e}= 9.109\times 10^{-31} kg.

{e \over m}= 1.75\times 10^{11} {C \over kg}=1.75\times 10^{8} {C \over g}
