Convert joules (J), calories (cal), kilowatt-hours (kWh), BTU, and other energy units. Energy is the capacity to do work; the joule (J) is the SI unit (1 J = 1 N·m). Nutritional calories and electrical kWh use different reference definitions tied to joules.
This energy converter transforms values from Joules (J) to Kilowatt Hours (kWh). Results update instantly using the exact conversion factor.
The joule (J) is the SI unit of energy (1 J = 1 N·m).
The kilowatt-hour (kWh) measures electrical energy: 1 kWh = 3.6 × 10⁶ J.
1 J ÷ 3600000 = 0.00000028 kWh
kWh = J ÷ 3600000
To convert J to kWh, divide the value in J by 3600000 (since 1 J = 0.00000028 kWh). Equivalently, multiply by 0.00000028. Example: 1 J = 1 J × 0.00000028 = 0.00000028 kWh.
10 J = 0.00000278 kWh ÷ 3600000 = 10 J
