Torque vs energy: Foot-pound (ft·lbf) is used both as a unit of ENERGY — where 1 N·m = 1 joule exactly — and as a unit of TORQUE (a twisting force × distance). This page converts the ENERGY meaning, so the figures above are correct for work and heat. A newton-metre of torque is a different physical quantity and does NOT convert into joules, kilowatt-hours or calories.
Foot-pound to Calorie conversion formula
To convert foot-pound to calorie, multiply by 0.3240483:
calorie = foot-pound × 0.3240483
Going the other way, 1 calorie = 3.08596 foot-pound, so
foot-pound = calorie × 3.08596.

About foot-pound and calorie
Foot-pound: A foot-pound is the energy of one pound-force acting over one foot — about 1.3558 joules. The same number (as the pound-foot, lbf·ft) is also the common US unit of TORQUE.
Calorie: A (small/gram) calorie is roughly the heat needed to raise 1 g of water by 1 °C — the thermochemical calorie is exactly 4.184 J. The food "Calorie" is actually a kilocalorie.
