电容是系统存储电荷的能力。它是在法拉德（F）中测量的。
1 zF = 1.0000e-21 esu/F
1 esu/F = 1,000,000,000,000,000,100,000 zF
例子:
将15 Zeptofarad转换为ESU PER FAIRAD：
15 zF = 1.5000e-20 esu/F
| Zeptofarad | ESU PER FAIRAD |
|---|---|
| 0.01 zF | 1.0000e-23 esu/F |
| 0.1 zF | 1.0000e-22 esu/F |
| 1 zF | 1.0000e-21 esu/F |
| 2 zF | 2.0000e-21 esu/F |
| 3 zF | 3.0000e-21 esu/F |
| 5 zF | 5.0000e-21 esu/F |
| 10 zF | 1.0000e-20 esu/F |
| 20 zF | 2.0000e-20 esu/F |
| 30 zF | 3.0000e-20 esu/F |
| 40 zF | 4.0000e-20 esu/F |
| 50 zF | 5.0000e-20 esu/F |
| 60 zF | 6.0000e-20 esu/F |
| 70 zF | 7.0000e-20 esu/F |
| 80 zF | 8.0000e-20 esu/F |
| 90 zF | 9.0000e-20 esu/F |
| 100 zF | 1.0000e-19 esu/F |
| 250 zF | 2.5000e-19 esu/F |
| 500 zF | 5.0000e-19 esu/F |
| 750 zF | 7.5000e-19 esu/F |
| 1000 zF | 1.0000e-18 esu/F |
| 10000 zF | 1.0000e-17 esu/F |
| 100000 zF | 1.0000e-16 esu/F |
