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 = 1.0000e-6 MF
1 MF = 1,000,000 F
例子:
将15 指纹转换为兆：
15 F = 1.5000e-5 MF
| 指纹 | 兆 |
|---|---|
| 0.01 F | 1.0000e-8 MF |
| 0.1 F | 1.0000e-7 MF |
| 1 F | 1.0000e-6 MF |
| 2 F | 2.0000e-6 MF |
| 3 F | 3.0000e-6 MF |
| 5 F | 5.0000e-6 MF |
| 10 F | 1.0000e-5 MF |
| 20 F | 2.0000e-5 MF |
| 30 F | 3.0000e-5 MF |
| 40 F | 4.0000e-5 MF |
| 50 F | 5.0000e-5 MF |
| 60 F | 6.0000e-5 MF |
| 70 F | 7.0000e-5 MF |
| 80 F | 8.0000e-5 MF |
| 90 F | 9.0000e-5 MF |
| 100 F | 1.0000e-4 MF |
| 250 F | 0 MF |
| 500 F | 0.001 MF |
| 750 F | 0.001 MF |
| 1000 F | 0.001 MF |
| 10000 F | 0.01 MF |
| 100000 F | 0.1 MF |
