Calculator for Planck Units

Conversion of common physical units into Planck units.

The Planck units form a natural, universal and fundamental system for physical quantities. They were named after Max Planck, the founder of quantum mechanics. These units represent the limits to which we can distinguish cause and effect. Beyond that, our physical laws are no longer applicable. They therefore stand for extreme values, mostly extremely small, sometimes extremely large, often beyond human imagination.

The Planck units can be derived from these natural constants:
SymbolNatural constantMeaningValue
GGravitational constantStrength of gravity6.6743*10-11 m³/(kg*s²)
cSpeed of LightVelocity of massless particles (like photons) in vacuum299792458 m/s
