How to Convert Kilowatt-Hours to Joules
Converting kilowatt-hours to joules expresses electrical energy in SI units. One kilowatt-hour equals 3,600,000 joules (3.6 megajoules).
To convert kWh to joules, multiply the kWh value by 3,600,000. For example, 1 kWh x 3,600,000 = 3,600,000 J. This conversion helps understand energy consumption in scientific terms.
Kilowatt-hours are common on electricity bills, while joules are the scientific standard.
