About Kilowatt-hours and Joules

One kilowatt-hour equals exactly 3,600,000 joules (3.6 megajoules). The kilowatt-hour is the standard unit used by electricity meters and utility bills, while joules are required for physics calculations. A typical home uses 10,000-30,000 kWh per year — equivalent to 36-108 gigajoules. Engineers calculating energy storage, efficiency, and conversion losses must work in joules, making this conversion essential in power systems engineering, battery design, and renewable energy analysis.
