How to convert kilojoules 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 = kJ × 737.5621493One kilojoule is 737.5621493 foot-pounds force, so a single multiplication converts any value.
7,375.62 ft·lbf ≈ 10 × 737.5621493Energy 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.
