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).
About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert kilocalories to feet-pounds
1 kilocalorie is equal to 3085.96003257607845 feet-pound when both are expressed in joule-equivalents:
1 kcal = (4,184 J ÷ 1.3558179483314003 J) ftlb = 3085.96003257607845 ftlb
Each kilocalorie is defined as 4,184 J and each feet-pound as 1.3558179483314003 J in this tool, so one kcal equals 4,184 ÷ 1.3558179483314003 ftlb = 3085.96003257607845 ftlb.
Let d(kcal) be the numeric amount in Kilocalorie (kcal), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(kcal) × (4,184 / 1.3558179483314003)
Equivalently, divide by how many kcal fit into one ftlb (joules per ftlb divided by joules per kcal):
d(ftlb) = d(kcal) ÷ 0.00032404826681
Or: feet-pound = kilocalorie ÷ 0.00032404826681
Examples
Example #1: Convert 1 kcal to feet-pound
1 kcal = 1 kcal × (4,184/1.3558179483314003) ftlb = 3085.96003258 ftlb
1 kcal = 1 kcal ÷ 0.00032404826681 = 3085.96003258 ftlb
Example #2: Convert 10 kcal to feet-pound
10 kcal = 10 kcal × (4,184/1.3558179483314003) ftlb = 30859.6003258 ftlb
10 kcal = 10 kcal ÷ 0.00032404826681 = 30859.6003258 ftlb
Summary
To convert Kilocalorie to Feet-Pound, multiply the value in kcal by the ratio of joules per kcal divided by joules per ftlb. Equivalently: value_ftlb = value_kcal × (4184 / 1.3558179483314003). Numerically, 1 kcal equals 3085.9600325760784 ftlb.
Relationship context
You are converting between food / nutrition energy (calories) (Kilocalories) and US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds). All values are mapped through joules first. The numeric factor is 3.085960e+3.
