电容是系统存储电荷的能力。它是在法拉德（F）中测量的。
1 H/F = 1 W/F
1 W/F = 1 H/F
例子:
将15 亨利·普拉德转换为瓦特每危险：
15 H/F = 15 W/F
| 亨利·普拉德 | 瓦特每危险 |
|---|---|
| 0.01 H/F | 0.01 W/F |
| 0.1 H/F | 0.1 W/F |
| 1 H/F | 1 W/F |
| 2 H/F | 2 W/F |
| 3 H/F | 3 W/F |
| 5 H/F | 5 W/F |
| 10 H/F | 10 W/F |
| 20 H/F | 20 W/F |
| 30 H/F | 30 W/F |
| 40 H/F | 40 W/F |
| 50 H/F | 50 W/F |
| 60 H/F | 60 W/F |
| 70 H/F | 70 W/F |
| 80 H/F | 80 W/F |
| 90 H/F | 90 W/F |
| 100 H/F | 100 W/F |
| 250 H/F | 250 W/F |
| 500 H/F | 500 W/F |
| 750 H/F | 750 W/F |
| 1000 H/F | 1,000 W/F |
| 10000 H/F | 10,000 W/F |
| 100000 H/F | 100,000 W/F |
