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