To the Content of Planck Units

Based on the slightly revised Planck system of units the length, time, mass, temperature, and two dimensionless constants, one of which is the inverse of the fine structure constant, a new system of constants which is alternative to the system c, h, G, k, me and e is proposed: to the speed of light and constants of Planck, Newton, Boltzmann, the mass and charge of electron, respectively. It is shown that the Planck system of units has the same content with the coefficients of dimensionalities, which are introduced to give the corresponding dimensional content to physical quantities, and the constants c, h̄, G and k are the combinations of the coefficients of dimensionalities.
