I can define my units so that the speed of light in a vacuum is 1. I can also define my units so that 1 unit of mass is equal to 1 unit of energy.
In either case I will have a "c"; the c in E = m c^2 in the former, for example. *That* c is a dimensionless number-- hence interesting-- and that it is 1 is definitely interesting.
