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 Megajoule
One megajoule is 1,000,000 J. It is common in fuel-content and engineering thermal calculations.
How to convert kilowatt-hour (thermal) to megajoules
1 kilowatt-hour (thermal) is equal to 3.6 megajoule when both are expressed in joule-equivalents:
1 kwh_th = (3,600,000 J ÷ 1,000,000 J) mj = 3.6 mj
Each kilowatt-hour (thermal) is defined as 3,600,000 J and each megajoule as 1,000,000 J in this tool, so one kwh_th equals 3,600,000 ÷ 1,000,000 mj = 3.6 mj.
Let d(kwh_th) be the numeric amount in Kilowatt-hour (thermal) (kwh_th), and d(mj) the amount in Megajoule (mj). Then:
d(mj) = d(kwh_th) × (3,600,000 / 1,000,000)
Equivalently, divide by how many kwh_th fit into one mj (joules per mj divided by joules per kwh_th):
d(mj) = d(kwh_th) ÷ 0.27777777777778
Or: megajoule = kilowatt-hour (thermal) ÷ 0.27777777777778
Examples
Example #1: Convert 1 kwh_th to megajoule
1 kwh_th = 1 kwh_th × (3,600,000/1,000,000) mj = 3.6 mj
1 kwh_th = 1 kwh_th ÷ 0.27777777777778 = 3.6 mj
Example #2: Convert 10 kwh_th to megajoule
10 kwh_th = 10 kwh_th × (3,600,000/1,000,000) mj = 36 mj
10 kwh_th = 10 kwh_th ÷ 0.27777777777778 = 36 mj
Summary
To convert Kilowatt-hour (thermal) to Megajoule, multiply the value in kwh_th by the ratio of joules per kwh_th divided by joules per mj. Equivalently: value_mj = value_kwh_th × (3600000 / 1000000). Numerically, 1 kwh_th equals 3.6 mj.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt-hour (thermal)) and SI energy (joules) (Megajoules). All values are mapped through joules first. The numeric factor is 3.600000e+0.
