I don't believe the meter is defined in terms of the speed of light? Other natural units are, but not the meter. Furthermore, mu naught has SI base units without any added proportionality, so I don't see how there is room for manipulation.
Hello all,
While I understand the significance of natural units, I am wondering why, in SI units, we are able to assign μ0 an exact value. The speed of light is experimentally determined in m/s, and given the relationship derived from Maxwell's equations, we know that c^2 = 1/√(ε0μ0). Thus by...
