电容是系统存储电荷的能力。它是在法拉德(F)中测量的。
1 V·F = 1 A·s/V 
1 A·s/V = 1 V·F 
例子: 
将15 伏特转换为每伏的安培第二:
15 V·F = 15 A·s/V 
| 伏特 | 每伏的安培第二 | 
|---|---|
| 0.01 V·F | 0.01 A·s/V | 
| 0.1 V·F | 0.1 A·s/V | 
| 1 V·F | 1 A·s/V | 
| 2 V·F | 2 A·s/V | 
| 3 V·F | 3 A·s/V | 
| 5 V·F | 5 A·s/V | 
| 10 V·F | 10 A·s/V | 
| 20 V·F | 20 A·s/V | 
| 30 V·F | 30 A·s/V | 
| 40 V·F | 40 A·s/V | 
| 50 V·F | 50 A·s/V | 
| 60 V·F | 60 A·s/V | 
| 70 V·F | 70 A·s/V | 
| 80 V·F | 80 A·s/V | 
| 90 V·F | 90 A·s/V | 
| 100 V·F | 100 A·s/V | 
| 250 V·F | 250 A·s/V | 
| 500 V·F | 500 A·s/V | 
| 750 V·F | 750 A·s/V | 
| 1000 V·F | 1,000 A·s/V | 
| 10000 V·F | 10,000 A·s/V | 
| 100000 V·F | 100,000 A·s/V |
