About Joule
The joule is the SI unit of energy. All other units here are converted through fixed joule equivalents.
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 joules to kilowatt-hour (thermal)
1 joule is equal to 2.77777778e-7 kilowatt-hour (thermal) when both are expressed in joule-equivalents:
1 j = (1 J ÷ 3,600,000 J) kwh_th = 2.77777778e-7 kwh_th
Each joule is defined as 1 J and each kilowatt-hour (thermal) as 3,600,000 J in this tool, so one j equals 1 ÷ 3,600,000 kwh_th = 2.77777778e-7 kwh_th.
Let d(j) be the numeric amount in Joule (j), and d(kwh_th) the amount in Kilowatt-hour (thermal) (kwh_th). Then:
d(kwh_th) = d(j) × (1 / 3,600,000)
Equivalently, divide by how many j fit into one kwh_th (joules per kwh_th divided by joules per j):
d(kwh_th) = d(j) ÷ 3600000
Or: kilowatt-hour (thermal) = joule ÷ 3600000
Examples
Example #1: Convert 1 j to kilowatt-hour (thermal)
1 j = 1 j × (1/3,600,000) kwh_th = 0.0000002778 kwh_th
1 j = 1 j ÷ 3600000 = 0.0000002778 kwh_th
Example #2: Convert 10 j to kilowatt-hour (thermal)
10 j = 10 j × (1/3,600,000) kwh_th = 0.0000027778 kwh_th
10 j = 10 j ÷ 3600000 = 0.0000027778 kwh_th
Summary
To convert Joule to Kilowatt-hour (thermal), multiply the value in j by the ratio of joules per j divided by joules per kwh_th. Equivalently: value_kwh_th = value_j × (1 / 3600000). Numerically, 1 j equals 2.7777777777777776e-7 kwh_th.
Relationship context
You are converting between SI energy (joules) (Joules) and electrical energy (watt-hours) (Kilowatt-hour (thermal)). All values are mapped through joules first. The numeric factor is 2.777778e-7.
