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 Joule
The joule is the SI unit of energy. All other units here are converted through fixed joule equivalents.
How to convert kilowatt-hour (thermal) to joules
1 kilowatt-hour (thermal) is equal to 3600000 joule when both are expressed in joule-equivalents:
1 kwh_th = (3,600,000 J ÷ 1 J) j = 3600000 j
Each kilowatt-hour (thermal) is defined as 3,600,000 J and each joule as 1 J in this tool, so one kwh_th equals 3,600,000 ÷ 1 j = 3600000 j.
Let d(kwh_th) be the numeric amount in Kilowatt-hour (thermal) (kwh_th), and d(j) the amount in Joule (j). Then:
d(j) = d(kwh_th) × (3,600,000 / 1)
Equivalently, divide by how many kwh_th fit into one j (joules per j divided by joules per kwh_th):
d(j) = d(kwh_th) ÷ 2.77777778e-7
Or: joule = kilowatt-hour (thermal) ÷ 2.77777778e-7
Examples
Example #1: Convert 1 kwh_th to joule
1 kwh_th = 1 kwh_th × (3,600,000/1) j = 3600000 j
1 kwh_th = 1 kwh_th ÷ 2.77777778e-7 = 3600000 j
Example #2: Convert 10 kwh_th to joule
10 kwh_th = 10 kwh_th × (3,600,000/1) j = 36000000 j
10 kwh_th = 10 kwh_th ÷ 2.77777778e-7 = 36000000 j
Summary
To convert Kilowatt-hour (thermal) to Joule, multiply the value in kwh_th by the ratio of joules per kwh_th divided by joules per j. Equivalently: value_j = value_kwh_th × (3600000 / 1). Numerically, 1 kwh_th equals 3600000 j.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt-hour (thermal)) and SI energy (joules) (Joules). All values are mapped through joules first. The numeric factor is 3.600000e+6.
