Units explained
Planck Mass
The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.
Introduced by Max Planck in 1899 as part of a system of natural units.
Theoretical physics and quantum-gravity research.
Defined by Planck in 1899 from fundamental constants.
Ounce
The (avoirdupois) ounce (oz) equals one-sixteenth of a pound, about 28.35 grams.
From Latin 'uncia', meaning a twelfth part.
US food portions, postal weights, and boxing weight classes.
Standardized as 1/16 of the international pound from 1959.
