功率是完成工作或能量转移的速度。它以瓦（w）为单位进行测量。
1 Wh/s = 3,600 J/s
1 J/s = 0 Wh/s
例子:
将15 瓦特每秒转换为每秒焦耳：
15 Wh/s = 54,000 J/s
| 瓦特每秒 | 每秒焦耳 |
|---|---|
| 0.01 Wh/s | 36 J/s |
| 0.1 Wh/s | 360 J/s |
| 1 Wh/s | 3,600 J/s |
| 2 Wh/s | 7,200 J/s |
| 3 Wh/s | 10,800 J/s |
| 5 Wh/s | 18,000 J/s |
| 10 Wh/s | 36,000 J/s |
| 20 Wh/s | 72,000 J/s |
| 30 Wh/s | 108,000 J/s |
| 40 Wh/s | 144,000 J/s |
| 50 Wh/s | 180,000 J/s |
| 60 Wh/s | 216,000 J/s |
| 70 Wh/s | 252,000 J/s |
| 80 Wh/s | 288,000 J/s |
| 90 Wh/s | 324,000 J/s |
| 100 Wh/s | 360,000 J/s |
| 250 Wh/s | 900,000 J/s |
| 500 Wh/s | 1,800,000 J/s |
| 750 Wh/s | 2,700,000 J/s |
| 1000 Wh/s | 3,600,000 J/s |
| 10000 Wh/s | 36,000,000 J/s |
| 100000 Wh/s | 360,000,000 J/s |
