How to Convert Joules to Kilowatt-hours
Basic Conversion Formula
kWh = J / 3,600,000
kWh = Energy (kilowatt-hours)
J = Energy (joules)
Practical Example
Given:
- Energy = 7,200,000 joules
Solution:
kWh = 7,200,000 J / 3,600,000 = 2 kWh
Explanation of Terms
- kWh (Kilowatt-hour): A unit of energy equivalent to one kilowatt of power used for one hour.
- J (Joules): The unit of energy. One joule is the energy transferred when one newton of force is applied over a distance of one meter.
