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