hbar = e^2*z0
hbar = [(1.6021766(34) x 10^-19 A-s)^2] * (3.767303134… x 10^2 kg-m^2/A^2-s^3)
hbar = 9.6705540(00) x 10^-36 kg-m^2/s

hbar = e^2/e0*c
hbar = [(1.6021766(34) x 10^-19 A-s)^2] / (8.854187817… x 10^-12 A^2-s^4/kg-m^3) * (2.99792458 x 10^8 m/s)
hbar = 9.6705540(00) x 10^-36 kg-m^2/s

hbar = e^2*u0*c
hbar = [(1.6021766(34) x 10^-19 A-s)^2] * (1.256637061… x 10^-6 kg-m/A^2-s^2) * (2.99792458 x 10^8 m/s)
hbar = 9.6705540(00) x 10^-36 kg-m^2/s

hbar = h*(2*alpha)
hbar = (6.6260701(50) x 10^-34 kg-m^2/s-rad) * [(2.00000000 x 10^0 rad/sr) * (7.2973525(66) x 10^-3 sr)]
hbar = 9.6705540(00) x 10^-36 kg-m^2/s
