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 = 1,000 mV
1 mV = 0.001 W/A
例子:
将15 瓦特每安培转换为毫伏：
15 W/A = 15,000 mV
| 瓦特每安培 | 毫伏 |
|---|---|
| 0.01 W/A | 10 mV |
| 0.1 W/A | 100 mV |
| 1 W/A | 1,000 mV |
| 2 W/A | 2,000 mV |
| 3 W/A | 3,000 mV |
| 5 W/A | 5,000 mV |
| 10 W/A | 10,000 mV |
| 20 W/A | 20,000 mV |
| 30 W/A | 30,000 mV |
| 40 W/A | 40,000 mV |
| 50 W/A | 50,000 mV |
| 60 W/A | 60,000 mV |
| 70 W/A | 70,000 mV |
| 80 W/A | 80,000 mV |
| 90 W/A | 90,000 mV |
| 100 W/A | 100,000 mV |
| 250 W/A | 250,000 mV |
| 500 W/A | 500,000 mV |
| 750 W/A | 750,000 mV |
| 1000 W/A | 1,000,000 mV |
| 10000 W/A | 10,000,000 mV |
| 100000 W/A | 100,000,000 mV |
