Acceleration due to gravity g = 9.80665 m/s2
Avagadro's number NA = 6.022137 x 1023
Faraday Constant = F = 96,484 C mol-1 = 96,500
Masses of Subatomic Particles: electron me = 9.10939897 x 10-31 kg = 5.4857991 x 10-4 u
proton mp = 1.6726231 x 10-27 kg = 1.0072765 u
neutron mn = 1.6749286 x 10-27 kg = 1.0086649 u
