Example
You may wish to store any of the following commonly used constants in K4 to K7.
K4 Dielectric Constant of Vacuum e0 = 8.85419 x 1CT12
Ks Gas Constant R = 8.2054 x 10
K6 Light Velocity of Vacuum C = 2.99792 x 108

Gas Equilibrium
If you had stored the gas constant (R) in Ks, you would calculate gas pressure as
follows:
PV = nRT T * 300°K, n = 0.5mol, V = 10C
