How Many Joules in a Kilowatt-Hour?
クイックアンサー
There are 3,600,000 joules in one kilowatt-hour.
1 kWh = 1,000 W × 3,600 s = 3,600,000 J
変換の理解
One kilowatt-hour = 1,000 watts × 3,600 seconds = 3,600,000 joules (3.6 MJ). This is the exact conversion because watts (joules/second) × seconds = joules, and kWh = 1,000 W × 3,600 s. The joule is the SI unit of energy.
公式
1 kWh = 1,000 W × 3,600 s = 3,600,000 J
