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).
About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
How to convert kilowatt-hour (thermal) to therm
1 kilowatt-hour (thermal) is equal to 0.03412141633128 therm when both are expressed in joule-equivalents:
1 kwh_th = (3,600,000 J ÷ 105,505,585.262 J) therm = 0.03412141633128 therm
Each kilowatt-hour (thermal) is defined as 3,600,000 J and each therm as 105,505,585.262 J in this tool, so one kwh_th equals 3,600,000 ÷ 105,505,585.262 therm = 0.03412141633128 therm.
Let d(kwh_th) be the numeric amount in Kilowatt-hour (thermal) (kwh_th), and d(therm) the amount in Therm (therm). Then:
d(therm) = d(kwh_th) × (3,600,000 / 105,505,585.262)
Equivalently, divide by how many kwh_th fit into one therm (joules per therm divided by joules per kwh_th):
d(therm) = d(kwh_th) ÷ 29.30710701722222
Or: therm = kilowatt-hour (thermal) ÷ 29.30710701722222
Examples
Example #1: Convert 1 kwh_th to therm
1 kwh_th = 1 kwh_th × (3,600,000/105,505,585.262) therm = 0.0341214163 therm
1 kwh_th = 1 kwh_th ÷ 29.30710701722222 = 0.0341214163 therm
Example #2: Convert 10 kwh_th to therm
10 kwh_th = 10 kwh_th × (3,600,000/105,505,585.262) therm = 0.3412141633 therm
10 kwh_th = 10 kwh_th ÷ 29.30710701722222 = 0.3412141633 therm
Summary
To convert Kilowatt-hour (thermal) to Therm, multiply the value in kwh_th by the ratio of joules per kwh_th divided by joules per therm. Equivalently: value_therm = value_kwh_th × (3600000 / 105505585.262). Numerically, 1 kwh_th equals 0.03412141633127942 therm.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt-hour (thermal)) and US / imperial engineering units (BTU, therm, ft·lb) (Therm). All values are mapped through joules first. The numeric factor is 3.412142e-2.
