How Many Megajoules in a Kilowatt-Hour?
快速解答
There are 3.6 megajoules in one kilowatt-hour.
1 kWh = 3.6 MJ
理解转换
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
常见示例
| 描述 | 值 |
|---|---|
| A 60W bulb for 1 hour (0.06 kWh) | 0.216 MJ |
| Gasoline energy density | ≈34 MJ/L ≈ 9.4 kWh/L |
| Daily human energy expenditure | ≈8–10 MJ (2,000–2,400 kcal) |
