About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
About Kilowatt-hour (thermal)
Kilowatt-hour (thermal) is shown as a thermal-energy label and uses the same joule definition as kWh (3.6 MJ).
How to convert feet-pounds to kilowatt-hour (thermal)
1 feet-pound is equal to 3.76616097e-7 kilowatt-hour (thermal) when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 3,600,000 J) kwh_th = 3.76616097e-7 kwh_th
Each feet-pound is defined as 1.3558179483314003 J and each kilowatt-hour (thermal) as 3,600,000 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 3,600,000 kwh_th = 3.76616097e-7 kwh_th.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(kwh_th) the amount in Kilowatt-hour (thermal) (kwh_th). Then:
d(kwh_th) = d(ftlb) × (1.3558179483314003 / 3,600,000)
Equivalently, divide by how many ftlb fit into one kwh_th (joules per kwh_th divided by joules per ftlb):
d(kwh_th) = d(ftlb) ÷ 2655223.73739815549925
Or: kilowatt-hour (thermal) = feet-pound ÷ 2655223.73739815549925
Examples
Example #1: Convert 1 ftlb to kilowatt-hour (thermal)
1 ftlb = 1 ftlb × (1.3558179483314003/3,600,000) kwh_th = 0.0000003766 kwh_th
1 ftlb = 1 ftlb ÷ 2655223.73739815549925 = 0.0000003766 kwh_th
Example #2: Convert 10 ftlb to kilowatt-hour (thermal)
10 ftlb = 10 ftlb × (1.3558179483314003/3,600,000) kwh_th = 0.0000037662 kwh_th
10 ftlb = 10 ftlb ÷ 2655223.73739815549925 = 0.0000037662 kwh_th
Summary
To convert Feet-Pound to Kilowatt-hour (thermal), multiply the value in ftlb by the ratio of joules per ftlb divided by joules per kwh_th. Equivalently: value_kwh_th = value_ftlb × (1.3558179483314003 / 3600000). Numerically, 1 ftlb equals 3.766160967587223e-7 kwh_th.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds) and electrical energy (watt-hours) (Kilowatt-hour (thermal)). All values are mapped through joules first. The numeric factor is 3.766161e-7.
