The Energy Unit Conversion describes the rate in which the 3 main energy units supported by Mekanism (EU, FE, J) can be converted.
Note that RF is completely equivalent to FE.
Mekanism supports up to 2^64-1 or roughly 1.8x10^19 Joules of energy in any regular container. This would be displayed as 18 EFE in game (exa-FE).
The list of prefixes for energy, sorted by size from the smallest to largest, is :
f < p < n < µ < m < [nothing] < k < M < G < T < P < E < Z < Y
Where each level is 1000x bigger/smaller than the adjacent ones.
