About Calorie
The small calorie (cal) is 4.184 J in this converter (thermochemical). Do not confuse with the dietary kilocalorie (kcal).
About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert calories to feet-pounds
1 calorie is equal to 3.08596003257608 feet-pound when both are expressed in joule-equivalents:
1 cal = (4.184 J ÷ 1.3558179483314003 J) ftlb = 3.08596003257608 ftlb
Each calorie is defined as 4.184 J and each feet-pound as 1.3558179483314003 J in this tool, so one cal equals 4.184 ÷ 1.3558179483314003 ftlb = 3.08596003257608 ftlb.
Let d(cal) be the numeric amount in Calorie (cal), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(cal) × (4.184 / 1.3558179483314003)
Equivalently, divide by how many cal fit into one ftlb (joules per ftlb divided by joules per cal):
d(ftlb) = d(cal) ÷ 0.32404826680961
Or: feet-pound = calorie ÷ 0.32404826680961
Examples
Example #1: Convert 1 cal to feet-pound
1 cal = 1 cal × (4.184/1.3558179483314003) ftlb = 3.0859600326 ftlb
1 cal = 1 cal ÷ 0.32404826680961 = 3.0859600326 ftlb
Example #2: Convert 10 cal to feet-pound
10 cal = 10 cal × (4.184/1.3558179483314003) ftlb = 30.8596003258 ftlb
10 cal = 10 cal ÷ 0.32404826680961 = 30.8596003258 ftlb
Summary
To convert Calorie to Feet-Pound, multiply the value in cal by the ratio of joules per cal divided by joules per ftlb. Equivalently: value_ftlb = value_cal × (4.184 / 1.3558179483314003). Numerically, 1 cal equals 3.0859600325760783 ftlb.
Relationship context
You are converting between food / nutrition energy (calories) (Calories) and US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds). All values are mapped through joules first. The numeric factor is 3.085960e+0.
