From the article:

Two important features of General Relativity are the curvature of spacetime and the distribution of mass-energy which causes it. How are the two related? To get from an energy density to a curvature quantity multiply the energy density by G/c4. This is the reciprocal of the Planck force, which mediates between energy density and curvature.

I've never heard the term 'Planck force'. Googling for it finds refrences on planck.com, and various other sources of 'alternative physics' ideas, but not elsewhere...

-- The Anome

Planck's force is just the unit of force in Planck units. It's not a force but rather a unit of measure of force which happens to be one in God's units. Restored the paragraph. Someone needs to copyedit for reciprocal.
