# Foe

A foe is a unit of energy equal to 10^44 joules (= 9.478x10^40 BTU) that was coined by physicist Gerry Brown of Stony Brook University. To measure the staggeringly immense amount of energy produced by a supernova, specialists occasionally use the "foe", an acronym derived from the phrase [ten to the power of] fifty-one ergs, or 10^51 ergs. This unit of measure is convenient because a supernova typically releases about one foe of observable energy in a very short period of time (which can be measured in seconds).

Foe
Symbol/abbreviation: foe
Unit of: ENERGY
ENERGY's base unit: joules (Non-SI/Derived Unit)
In relation to the base unit (joules), 1 Foe = 1.0E+44 joules.
