A:
You can also let the gravitational constant, G, be one to obtain standard Planck units. No changes whatever occur in the physics. Nature doesn't care what names we call her. However, for the physicist, setting Planck's constant and c to 1 reduces the amount of writing needed. This can save some used envelopes.
