The quantity of raw materials, fuel, or time required to produce one product or a certain amount of product. For example, the coke ratio, which indicates the amount of coke required to produce 1 ton of pig iron, is a typical example of an energy intensity unit. The intensity unit is the basis of a company's cost accounting and rationalization plans, and the lower the intensity unit, the more rational the production is.

生産物1個,あるいは一定量の生産物をつくるために必要とされる原材料や燃料,あるいは所要時間などの数量。たとえば銑鉄 1tをつくるために必要なコークスの量を示すコークス比はエネルギー原単位としてその代表的なものである。原単位は企業の原価計算や合理化計画などの基礎となる概念で,原単位が低くなればなるほど,それだけ生産が合理的に行われていることを意味する。
