Relative effectiveness factor (R.E. factor) is a measurement of an explosive's power for military demolitions purposes. It is used to compare an explosives effectiveness relative to TNT by weight only. This is so engineers can substitute one explosive for another when they are figuring out blasting equations that are designed for TNT. For example, If a timber cutting charge requires 1lb of TNT to work, it would take 0.6LB of PETN or 2.4LBS of Ammonium Nitrate to have the same effect.

Some examples of RE factors include:

Ammonium nitrate = 0.42
Black powder = 0.55
TNT = 1.00
C-4 = 1.34
Nitroglycerin = 1.50
RDX = 1.60
PETN = 1.66
Semtex = 1.66
HMX = 1.70
Hexanitrohexaazaisowurtzitane = 2.04
Octanitrocubane = 2.7
