Foe

Foe is a scientific unit used to quantify the most energetic events in the Universe. 1 Foe equals 10e44joules or 10e51 ergs (that's why it's called Foe or "[tenth power of]  F ifty- o ne  e rgs"). This is also rather convenient because the normal Type Ia supernovae usually releases energy equating between 1 and 2 Foe in under just a few seconds.

It's also worth noting that Foe has no plural form. Or to be precise it's always in plural as this is an abbreviation referring to "fifty-one erg s ".

Its conversion from joules is trivial and it's also compatible with the common scientific prefixes. So when you see terms like "5.5 kilo-Foe" then read it as 5500 Foe or 5.5 x 10e47 joules of energy.

Common Examples:
 * GBE of the smallest star: 0.16 mili-foe
 * Theoretical total mass-energy of the entire Earth: 5.4 mili-foe
 * GBE of the Sun: 6.9 mili-foe
 * Average power of a gamma ray burst: 0.5-1 foe
 * Energy content of a normal Type Ia supernova: 1-2 foe
 * Energy content of an average hypernova: 100 foe
 * Theoretical total mass-energy of the Sun: 1.8 kilo-foe
 * Estimated total mass-energy of the observable universe: 40 yotta-foe (4e69 J)
