one bit's worth of uncertainty, measured in nature's own logarithm instead of humanity's binary one.
means a nat is the unit of information or entropy you get when you use the natural logarithm (base e) instead of log base 2, which gives bits.
from short for natural unit, coined alongside nit and hartley in early information theory as mathematicians realized shannon's bit was just one arbitrary log-base choice among several.
conversion factor1 nat equals about 1.4427 bits
