Gentlemen:

Given:

Planck's constant hb 1.054572675E-27 g cm^2 sec^-1
gravitational constant G 6.6725985E-8 cm^3 sec^-2 g^-1
speed of light c 2.997924580E10 cm sec^-1

The following is list of some of the Planck scale parameters:

Planck length (hb G/c^3)^(1/2) 1.61605E-35 cm
Planck time (hb G/c^5)^(1/2) 5.39056E-44 sec
Planck mass (hb c/G)^(1/2) 2.17671E-08 g
Planck energy (hb c^5/G)^(1/2) 1.95610E-16 g cm^2 sec^-2
Planck momentum (hb c^3/G)^(1/2) 6.52483E+05 g cm sec^-1
Planck force (c^4/G) 1.21027E+49 g cm sec^-2
Planck density (c^5/(hb G^2) 5.15500E+93 g/cm^3
Planck acceleration (c^6/(hb G)) 1.03145E+97 cm/sec^2
Planck kinematic viscosity (c^7/(hb G))^(1/2) 5.56077E+53 cm^2/sec
Planck absolute viscosity (c^9/(hb G^3))^(1/2) 2.49779E+71 g cm^-1 sec^-1

It is difficult to say which has a 'physical meaning'.

Using dimensional units of mass, length & time
the constants hb, G, c can be arranged in an infinite number of possibilities.

hb = 1.054572675*10^(-27)
1.054572675`*^-27
G = 6.6725985*10^(-8 )
6.672598500000001`*^-8
c = 2.997924580*10^10
2.99792458`*^10
(hb G/c^3)^(1/2)
1.6160496497524128`*^-33
(hb G/c^5)^(1/2)
5.390561392149541`*^-44

Two out of three wrong isn't bad?

Thank you for the obvious corrections
