How to convert foot-pounds force to watt-hours
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.
Wh = ft·lbf × 0.0003766160968One foot-pound force is 0.0003766160968 watt-hours, so a single multiplication converts any value.
0.00376616 Wh ≈ 10 × 0.0003766160968Energy 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.
