Tonne of oil equivalent

The Tonne of oil equivalent (TOE) is a measure of energy. It is the quantity of energy released by burning one tonne (which is 1000 kilograms) of crude oil. Like BOE (Barrel of Oil Equivalent), TOE is used to quantify oil or gas in common terms. Because the energy content of crude oil varies, it is an approximate measure.
