Note that if the black hole radius is R = ( ℏ G / c 3) 1 / 2, the black hole mass is obtained from R = 2 G M / c 2 i.e. M = c 2 / G ⋅ ( ℏ G / c 3) 1 / 2 = ( ℏ c / G) 1 / 2 which is the same thing as the Compton wavelength ...
WebbSimilarly, the temperature is measured in degree celsius, and the same unit of measurement cannot be used to measure the length of a rod. Each quantity has to be measured in its own way. The magnitude and the measurement vary along with the quantity. Hence the need for the units of measurement for each quantity arises.
