About Watt Hour
One watt-hour is 3,600 J—the energy from 1 W for one hour. Common for small batteries and device ratings.
About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert watt hours to feet-pounds
1 watt hour is equal to 2655.22373739815521 feet-pound when both are expressed in joule-equivalents:
1 wh = (3,600 J ÷ 1.3558179483314003 J) ftlb = 2655.22373739815521 ftlb
Each watt hour is defined as 3,600 J and each feet-pound as 1.3558179483314003 J in this tool, so one wh equals 3,600 ÷ 1.3558179483314003 ftlb = 2655.22373739815521 ftlb.
Let d(wh) be the numeric amount in Watt Hour (wh), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(wh) × (3,600 / 1.3558179483314003)
Equivalently, divide by how many wh fit into one ftlb (joules per ftlb divided by joules per wh):
d(ftlb) = d(wh) ÷ 0.00037661609676
Or: feet-pound = watt hour ÷ 0.00037661609676
Examples
Example #1: Convert 1 wh to feet-pound
1 wh = 1 wh × (3,600/1.3558179483314003) ftlb = 2655.2237374 ftlb
1 wh = 1 wh ÷ 0.00037661609676 = 2655.2237374 ftlb
Example #2: Convert 10 wh to feet-pound
10 wh = 10 wh × (3,600/1.3558179483314003) ftlb = 26552.237374 ftlb
10 wh = 10 wh ÷ 0.00037661609676 = 26552.237374 ftlb
Summary
To convert Watt Hour to Feet-Pound, multiply the value in wh by the ratio of joules per wh divided by joules per ftlb. Equivalently: value_ftlb = value_wh × (3600 / 1.3558179483314003). Numerically, 1 wh equals 2655.223737398155 ftlb.
Relationship context
You are converting between electrical energy (watt-hours) (Watt Hours) and US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds). All values are mapped through joules first. The numeric factor is 2.655224e+3.
