Convert ft lb to cal

Foot-pound

A foot-pound is the work done by one pound-force acting through one foot.

Foot-pounds come from customary force and length units and remain common in US mechanical references.

ft-lb is used in mechanical work, impact energy, equipment specifications, torque-related documents, and engineering comparisons.

Calorie

A small calorie is a heat-energy unit equal to 4.184 joules.

Calories were widely used in heat measurement before joules became the standard scientific energy unit.

Small calories are used in chemistry examples, thermodynamics teaching, older references, and detailed heat calculations.

How to Convert Foot-pound to Calorie

Mathematically, calorie (cal) = foot-pound (ft·lbf) converted with the formula below.

1 ft·lbf = 0.324048 cal

1 cal = 3.08596 ft·lbf

Formula: value × 0.32404826681

Example: 15 ft·lbf = 4.860724 cal

1. Start with the energy value in foot-pounds.
2. Convert foot-pounds to joules using 1 ft-lb = 1.3558179483314004 J.
3. Use 4.184 J for each small calorie.
4. Divide the joule value by 4.184 to get calories.

Precision note: This converter uses 1 ft-lb = 1.3558179483314004 J and 1 cal = 4.184 J, giving 1 ft-lb = 0.3240482668 cal.

How many ft·lbf in cal and cal in ft·lbf
