About Kilowatt Hour
One kilowatt-hour is the energy from 1 kW of power for one hour: 1 kWh = 3,600,000 J. Utility bills and battery specs often use kWh.
About British Thermal Unit
The British thermal unit used here is the IT BTU: ≈ 1,055.056 J. It appears in HVAC, heating equipment, and US engineering data.
How to convert kilowatt hours to british thermal units
1 kilowatt hour is equal to 3412.14163312794199 british thermal unit when both are expressed in joule-equivalents:
1 kwh = (3,600,000 J ÷ 1,055.05585262 J) btu = 3412.14163312794199 btu
Each kilowatt hour is defined as 3,600,000 J and each british thermal unit as 1,055.05585262 J in this tool, so one kwh equals 3,600,000 ÷ 1,055.05585262 btu = 3412.14163312794199 btu.
Let d(kwh) be the numeric amount in Kilowatt Hour (kwh), and d(btu) the amount in British Thermal Unit (btu). Then:
d(btu) = d(kwh) × (3,600,000 / 1,055.05585262)
Equivalently, divide by how many kwh fit into one btu (joules per btu divided by joules per kwh):
d(btu) = d(kwh) ÷ 0.00029307107017
Or: british thermal unit = kilowatt hour ÷ 0.00029307107017
Examples
Example #1: Convert 1 kwh to british thermal unit
1 kwh = 1 kwh × (3,600,000/1,055.05585262) btu = 3412.14163313 btu
1 kwh = 1 kwh ÷ 0.00029307107017 = 3412.14163313 btu
Example #2: Convert 10 kwh to british thermal unit
10 kwh = 10 kwh × (3,600,000/1,055.05585262) btu = 34121.4163313 btu
10 kwh = 10 kwh ÷ 0.00029307107017 = 34121.4163313 btu
Summary
To convert Kilowatt Hour to British Thermal Unit, multiply the value in kwh by the ratio of joules per kwh divided by joules per btu. Equivalently: value_btu = value_kwh × (3600000 / 1055.05585262). Numerically, 1 kwh equals 3412.141633127942 btu.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt Hours) and US / imperial engineering units (BTU, therm, ft·lb) (British Thermal Units). All values are mapped through joules first. The numeric factor is 3.412142e+3.
