About Megajoule
One megajoule is 1,000,000 J. It is common in fuel-content and engineering thermal calculations.
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 megajoules to kilowatt-hour (thermal)
1 megajoule is equal to 0.27777777777778 kilowatt-hour (thermal) when both are expressed in joule-equivalents:
1 mj = (1,000,000 J ÷ 3,600,000 J) kwh_th = 0.27777777777778 kwh_th
Each megajoule is defined as 1,000,000 J and each kilowatt-hour (thermal) as 3,600,000 J in this tool, so one mj equals 1,000,000 ÷ 3,600,000 kwh_th = 0.27777777777778 kwh_th.
Let d(mj) be the numeric amount in Megajoule (mj), and d(kwh_th) the amount in Kilowatt-hour (thermal) (kwh_th). Then:
d(kwh_th) = d(mj) × (1,000,000 / 3,600,000)
Equivalently, divide by how many mj fit into one kwh_th (joules per kwh_th divided by joules per mj):
d(kwh_th) = d(mj) ÷ 3.6
Or: kilowatt-hour (thermal) = megajoule ÷ 3.6
Examples
Example #1: Convert 1 mj to kilowatt-hour (thermal)
1 mj = 1 mj × (1,000,000/3,600,000) kwh_th = 0.2777777778 kwh_th
1 mj = 1 mj ÷ 3.6 = 0.2777777778 kwh_th
Example #2: Convert 10 mj to kilowatt-hour (thermal)
10 mj = 10 mj × (1,000,000/3,600,000) kwh_th = 2.7777777778 kwh_th
10 mj = 10 mj ÷ 3.6 = 2.7777777778 kwh_th
Summary
To convert Megajoule to Kilowatt-hour (thermal), multiply the value in mj by the ratio of joules per mj divided by joules per kwh_th. Equivalently: value_kwh_th = value_mj × (1000000 / 3600000). Numerically, 1 mj equals 0.2777777777777778 kwh_th.
Relationship context
You are converting between SI energy (joules) (Megajoules) and electrical energy (watt-hours) (Kilowatt-hour (thermal)). All values are mapped through joules first. The numeric factor is 2.777778e-1.
