 Barrel of oil equivalent

Barrel of oil equivalent (BOE) is a unit of measure used to compare the energy content of various forms of energy, specifically fossil fuels. It expresses the amount of energy released by burning one barrel of crude oil, which is approximately 42 U.S. gallons (159 liters). The concept of BOE is useful in the energy sector because it allows for the conversion of different types of energy sources into a single standard for comparison.
