How Many Megajoules in a Kilowatt-Hour?
クイックアンサー
There are 3.6 megajoules in one kilowatt-hour.
1 kWh = 3.6 MJ
変換の理解
One kilowatt-hour equals exactly 3.6 megajoules (MJ). This relationship is clean because 1 kW = 1,000 J/s and 1 hour = 3,600 s, so 1 kWh = 1,000 × 3,600 J = 3,600,000 J = 3.6 MJ. Energy content of fuels is often expressed in MJ/kg.
公式
1 kWh = 3.6 MJ
一般的な例
