About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
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.
How to convert therm to kilowatt hours
1 therm is equal to 29.30710701722222 kilowatt hour when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 3,600,000 J) kwh = 29.30710701722222 kwh
Each therm is defined as 105,505,585.262 J and each kilowatt hour as 3,600,000 J in this tool, so one therm equals 105,505,585.262 ÷ 3,600,000 kwh = 29.30710701722222 kwh.
Let d(therm) be the numeric amount in Therm (therm), and d(kwh) the amount in Kilowatt Hour (kwh). Then:
d(kwh) = d(therm) × (105,505,585.262 / 3,600,000)
Equivalently, divide by how many therm fit into one kwh (joules per kwh divided by joules per therm):
d(kwh) = d(therm) ÷ 0.03412141633128
Or: kilowatt hour = therm ÷ 0.03412141633128
Examples
Example #1: Convert 1 therm to kilowatt hour
1 therm = 1 therm × (105,505,585.262/3,600,000) kwh = 29.3071070172 kwh
1 therm = 1 therm ÷ 0.03412141633128 = 29.3071070172 kwh
Example #2: Convert 10 therm to kilowatt hour
10 therm = 10 therm × (105,505,585.262/3,600,000) kwh = 293.071070172 kwh
10 therm = 10 therm ÷ 0.03412141633128 = 293.071070172 kwh
Summary
To convert Therm to Kilowatt Hour, multiply the value in therm by the ratio of joules per therm divided by joules per kwh. Equivalently: value_kwh = value_therm × (105505585.262 / 3600000). Numerically, 1 therm equals 29.307107017222222 kwh.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Therm) and electrical energy (watt-hours) (Kilowatt Hours). All values are mapped through joules first. The numeric factor is 2.930711e+1.
