Foot-pounds Force to Calories Converter
1 foot-pound force ≈ 0.324048267 calories
Energy and torque share these dimensions. For fastener torque see the Torque category, where the same quantity is written lbf·ft.
This is the small calorie. The "Calorie" on food labels is a kilocalorie, which is 1,000 of these.
1 foot-pound force equals 0.324048 calories
How to convert foot-pounds force to calories
Calories here are thermochemical (4.184 J), while BTU uses the International Table definition. A kilowatt-hour is energy (3.6 MJ), not power; a food Calorie is a kilocalorie.
cal = ft·lbf × 0.3240482668One foot-pound force is 0.3240482668 calories, so a single multiplication converts any value.
3.24048 cal ≈ 10 × 0.3240482668Energy and torque share these dimensions. For fastener torque see the Torque category, where the same quantity is written lbf·ft.
This is the small calorie. The "Calorie" on food labels is a kilocalorie, which is 1,000 of these.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
