About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
About Kilocalorie
The kilocalorie (kcal) is 1,000 calories in the nutrition sense—often labeled “Calorie” on food packaging. Here 1 kcal = 4,184 J (thermochemical calorie definition used in this tool).
How to convert feet-pounds to kilocalories
1 feet-pound is equal to 0.00032404826681 kilocalorie when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 4,184 J) kcal = 0.00032404826681 kcal
Each feet-pound is defined as 1.3558179483314003 J and each kilocalorie as 4,184 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 4,184 kcal = 0.00032404826681 kcal.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(kcal) the amount in Kilocalorie (kcal). Then:
d(kcal) = d(ftlb) × (1.3558179483314003 / 4,184)
Equivalently, divide by how many ftlb fit into one kcal (joules per kcal divided by joules per ftlb):
d(kcal) = d(ftlb) ÷ 3085.96003257607845
Or: kilocalorie = feet-pound ÷ 3085.96003257607845
Examples
Example #1: Convert 1 ftlb to kilocalorie
1 ftlb = 1 ftlb × (1.3558179483314003/4,184) kcal = 0.0003240483 kcal
1 ftlb = 1 ftlb ÷ 3085.96003257607845 = 0.0003240483 kcal
Example #2: Convert 10 ftlb to kilocalorie
10 ftlb = 10 ftlb × (1.3558179483314003/4,184) kcal = 0.0032404827 kcal
10 ftlb = 10 ftlb ÷ 3085.96003257607845 = 0.0032404827 kcal
Summary
To convert Feet-Pound to Kilocalorie, multiply the value in ftlb by the ratio of joules per ftlb divided by joules per kcal. Equivalently: value_kcal = value_ftlb × (1.3558179483314003 / 4184). Numerically, 1 ftlb equals 0.0003240482668096081 kcal.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds) and food / nutrition energy (calories) (Kilocalories). All values are mapped through joules first. The numeric factor is 3.240483e-4.
