Convert kg of oil equivalent to Foot-pound

Energy statistics reduce every fuel to a common yardstick. The tonne of oil equivalent is defined by the IEA as 41.868 GJ (11.63 MWh), roughly the energy in a tonne of crude; national energy balances are in Mtoe. The barrel of oil equivalent is used by oil companies, and its exact value varies between them, so figures are approximate. The tonne of coal equivalent is 29.3 GJ (7 million kcal), which Germany writes as SKE (Steinkohleeinheit). Natural gas is counted by volume or, as LNG, by mass: a billion cubic metres of gas is about 0.9 Mtoe.

The foot-pound is the work of a one-pound force over one foot, 1.356 J. It is used in the US for the muzzle energy of firearms and airguns (a .22 rifle delivers about 100 ft·lb, a hunting rifle 2,000–3,000) and for the impact energy of tools and hammers. Do not confuse it with the pound-foot of torque: the same product of force and distance, but nothing moves, so it is not energy.
