电势，也称为电压，是单位电荷的势能。它在伏特（v）中测量。
1 W/A = 1.0000e-6 MV
1 MV = 1,000,000 W/A
例子:
将15 瓦特每安培转换为纹身：
15 W/A = 1.5000e-5 MV
| 瓦特每安培 | 纹身 |
|---|---|
| 0.01 W/A | 1.0000e-8 MV |
| 0.1 W/A | 1.0000e-7 MV |
| 1 W/A | 1.0000e-6 MV |
| 2 W/A | 2.0000e-6 MV |
| 3 W/A | 3.0000e-6 MV |
| 5 W/A | 5.0000e-6 MV |
| 10 W/A | 1.0000e-5 MV |
| 20 W/A | 2.0000e-5 MV |
| 30 W/A | 3.0000e-5 MV |
| 40 W/A | 4.0000e-5 MV |
| 50 W/A | 5.0000e-5 MV |
| 60 W/A | 6.0000e-5 MV |
| 70 W/A | 7.0000e-5 MV |
| 80 W/A | 8.0000e-5 MV |
| 90 W/A | 9.0000e-5 MV |
| 100 W/A | 1.0000e-4 MV |
| 250 W/A | 0 MV |
| 500 W/A | 0.001 MV |
| 750 W/A | 0.001 MV |
| 1000 W/A | 0.001 MV |
| 10000 W/A | 0.01 MV |
| 100000 W/A | 0.1 MV |
