About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
About Calorie
The small calorie (cal) is 4.184 J in this converter (thermochemical). Do not confuse with the dietary kilocalorie (kcal).
How to convert feet-pounds to calories
1 feet-pound is equal to 0.32404826680961 calorie when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 4.184 J) cal = 0.32404826680961 cal
Each feet-pound is defined as 1.3558179483314003 J and each calorie as 4.184 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 4.184 cal = 0.32404826680961 cal.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(cal) the amount in Calorie (cal). Then:
d(cal) = d(ftlb) × (1.3558179483314003 / 4.184)
Equivalently, divide by how many ftlb fit into one cal (joules per cal divided by joules per ftlb):
d(cal) = d(ftlb) ÷ 3.08596003257608
Or: calorie = feet-pound ÷ 3.08596003257608
Examples
Example #1: Convert 1 ftlb to calorie
1 ftlb = 1 ftlb × (1.3558179483314003/4.184) cal = 0.3240482668 cal
1 ftlb = 1 ftlb ÷ 3.08596003257608 = 0.3240482668 cal
Example #2: Convert 10 ftlb to calorie
10 ftlb = 10 ftlb × (1.3558179483314003/4.184) cal = 3.2404826681 cal
10 ftlb = 10 ftlb ÷ 3.08596003257608 = 3.2404826681 cal
Summary
To convert Feet-Pound to Calorie, multiply the value in ftlb by the ratio of joules per ftlb divided by joules per cal. Equivalently: value_cal = value_ftlb × (1.3558179483314003 / 4.184). Numerically, 1 ftlb equals 0.3240482668096081 cal.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds) and food / nutrition energy (calories) (Calories). All values are mapped through joules first. The numeric factor is 3.240483e-1.
