Calories to Foot-pounds Force Converter
1 calorie ≈ 3.08596003 foot-pounds force
This is the small calorie. The "Calorie" on food labels is a kilocalorie, which is 1,000 of these.
Energy and torque share these dimensions. For fastener torque see the Torque category, where the same quantity is written lbf·ft.
1 calorie equals 3.08596 foot-pounds force
How to convert calories to foot-pounds force
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.
ft·lbf = cal × 3.085960033One calorie is 3.085960033 foot-pounds force, so a single multiplication converts any value.
30.8596 ft·lbf ≈ 10 × 3.085960033This is the small calorie. The "Calorie" on food labels is a kilocalorie, which is 1,000 of these.
Energy and torque share these dimensions. For fastener torque see the Torque category, where the same quantity is written lbf·ft.

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.
