Convert Kilocalories to Foot-pounds
1 kilocalorie is 3,085.960033 ft·lbf. One kilocalorie is exactly 3085.96003258 foot-pounds.
One kilocalorie is 3085.96 foot-pounds. To convert kilocalories to foot-pounds, multiply by 3085.96; to go the other way, divide by 3085.96 or multiply by 3.2405 × 10^-4. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand small calories, and what a food label means by "Calories" with a capital C.

How do you convert kilocalories to foot-pounds?
- 1.Take the measurement in kilocalories.
- 2.Multiply by 3085.96 — that is how many foot-pounds fit in one kilocalorie.
- 3.To go back the other way, divide by 3085.96, or multiply by 3.2405 × 10^-4.
Worked example: 25 kilocalories to foot-pounds
- Formula
- kcal × 3085.96 = ft·lbf
- Arithmetic
- 25 × 3085.96 = 77,149.000815 ft·lbf
- Answer
- 25 kcal = 77,149.000815 ft·lbf
The factor is rounded for display; the figure above is computed from the full value.

What is a kilocalorie?
A thousand small calories, and what a food label means by "Calories" with a capital C. A 2,000 calorie diet is 2,000 kcal, or 8.4 megajoules.
What is a foot-pound?
A pound-force acting through one foot. The same arithmetic as the torque unit of that name, and a different quantity: this one is work done, not twist applied.
How many foot-pounds are in a kilocalorie?
One kilocalorie is 3085.96 foot-pounds. Going the other way, one foot-pound is 3.2405 × 10^-4 kilocalories. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
