# PlanckUnitConversion

Convert a quantity into Planck units

Contributed by: Peter Burbery
 ResourceFunction["PlanckUnitConversion"][quantity] attempts to convert the specified quantity to Planck units.

## Details

Planck units are based on the fundamental constants of the speed of light c, the reduced Planck constant , the gravitational constant G, and the Boltzmann constant k.
 Planck Unit Definition Value in SI Base Units Length 1.616255⁣(18)*10-35m Mass 2.176434⁣(24)*10-8kg Time 5.391247⁣(60)*10-44s Temperature 1.416784⁣(16)*1032K
ResourceFunction["PlanckUnitConversion"] will output a unit in Planck units (Planck time, length, mass and temperature).
In ResourceFunction["PlanckUnitConversion"][input], input must be a quantity such as Quantity[49,"Meters"] or Quantity["Meters"].
