1 ft·lbf ≈ 0.00128506746346 BTU
1 BTU ≈ 778.169262266 ft·lbf
Formula: BTU ≈ ft·lbf × 0.00128506746346
ft·lbf ≈ BTU × 778.169262266
Definitions: 1 ft·lbf = 1.35581794833 J; 1 BTU = 1055.05585262 J
The foot-pound (ft·lbf) is the work done by a force of one pound-force over a distance of one foot, about 1.356 joules. It is used in the United States for the muzzle energy of ammunition and for impact energy, and it should not be confused with the pound-foot, a unit of torque.
The British thermal unit (BTU) here is the International Table BTU, about 1,055 joules, roughly the energy needed to raise one pound of water by one degree Fahrenheit. It is used in the United States for heating and cooling equipment, fuel content and natural gas.
