One BTU is equal to how many ft-lbf?

Explanation:
Converting energy units between BTU and foot-pound-force uses their equivalence in joules. A BTU is about 1055.06 joules, while one foot-pound-force is about 1.35582 joules. Dividing gives 1055.06 J ÷ 1.35582 J/ft·lb_f ≈ 778.17 ft·lb_f. So one BTU equals roughly 778 ft·lb_f.
