Relative effectiveness factor or R.E. factor is a measurement of an explosive's power for military demolitions purposes. It is used to compare an explosive's effectiveness relative to TNT by weight only, TNT equivalent/kg (TNTe/kg). This enables engineers to substitute one explosive for another when they are calculating blasting equations that are designed for TNT. For example, if a timber cutting charge requires 1 kg of TNT to work, it would take 0.42 kg of ONC, 0.6 kg of PETN, 1.25 kg of ANFO, or 2.22 kg of AN to have the same effect.

Famous quotes containing the words relative and/or factor:
“The ungentlemanly expressions and gasconading conduct of yours relative to me yesterday was in true character of yourself and unmask you to the world and plainly show that they were ebullitions of a base mind ... and flow from a source devoid of every refined sentiment or delicate sensations.”
—Andrew Jackson (1767–1845)
“It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be.... This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.”
—Isaac Asimov (1920–1992)
