(a set of units based on Planck constant and other fundamental constants)

Planck units are a set of units based upon Planck constant and other fundamental constants, i.e., one type of natural units. Some of them, such as Planck length and Planck time reflect minimal scales regarding the regime of current physical laws. Others are within the range of everyday units.

tP ≡ √(ℏG/c5)
lP ≡ √(ℏG/c3)
mP ≡ √(ℏc/G)
EP ≡ mPc2
TP ≡ EP/KB
