The gravitational constant G can be expressed as [tex]G\, =\, \frac{lP^3}{mP.tP^2}[/tex] where lP = the Planck length, mP is the Planck mass and tP the Planck time. Since c can be expressed as [tex]\frac{lP}{tP}[/tex] we can state that [tex]G\, =\, \frac{c^2L}{m}[/tex] where L is a distance of 1 light second. Now we have scaled up the equation. We can go further and scale up G by using the unitless factor [tex]\frac{L}{lP}[/tex] that when multiplied with G will give a scaled up value. Since we then need to find m we can rearrange the equation with the new G value to be [tex]m\, =\, \frac{c^2L}{G}[/tex]. This scale then relates directly to the Planck scale but one that we can work with having units that are on the macroscopic scale. This should make it easier to work with energies that would be applicable to the Planck scale without any of the difficulties.
