The fundamental physical unit of length.
In comparison to macorscopic physical units such as the meter, the approximate value of the Planck length is meter.
Two important physical units of length induced by a mass are
where
is the speed of light;
is the gravitational constant;
Solving the equation
for yields the Planck mass
The corresponding Compton wavelength is given by the Planck length
fundamental scales (fundamental/natural physical units)
