The density of water is also temperature-dependent :)
My point is that the chain of determining the measurement of a natural value should start at the value, not at what we want it to be to then bend the value over backwards to be that then.
So the example doesn't fall apart with a temperature-/moisture-dependent constant:
The point is that the constant should not be arbitrarily changed to achieve a desired value. The constant should be measured/defined and stay as such.
