电阻是通过材料通过电流流动的对立。它以欧姆（ω）进行测量。
1 ρ = 1 Ω
1 Ω = 1 ρ
例子:
将15 电阻率转换为欧姆：
15 ρ = 15 Ω
| 电阻率 | 欧姆 |
|---|---|
| 0.01 ρ | 0.01 Ω |
| 0.1 ρ | 0.1 Ω |
| 1 ρ | 1 Ω |
| 2 ρ | 2 Ω |
| 3 ρ | 3 Ω |
| 5 ρ | 5 Ω |
| 10 ρ | 10 Ω |
| 20 ρ | 20 Ω |
| 30 ρ | 30 Ω |
| 40 ρ | 40 Ω |
| 50 ρ | 50 Ω |
| 60 ρ | 60 Ω |
| 70 ρ | 70 Ω |
| 80 ρ | 80 Ω |
| 90 ρ | 90 Ω |
| 100 ρ | 100 Ω |
| 250 ρ | 250 Ω |
| 500 ρ | 500 Ω |
| 750 ρ | 750 Ω |
| 1000 ρ | 1,000 Ω |
| 10000 ρ | 10,000 Ω |
