convertimate Cable resistance per length

Ohms per mile to ohms per kilometer

Type a value in Ω/mi to get it in Ω/km instantly.

6.307Ω/km

That's 1.21× as resistive as AWG 12 copper, while 2.5 mm² copper cable is 1.17× more resistive. A 10 m run carrying 10 A loses 1.261 V there and back.

What it means

How resistive is that cable?

DC resistance at 20 °C. Copper’s resistance rises about 0.4 % per °C; AC adds skin effect in thick conductors.

The math

How to convert Ω/mi to Ω/km

To convert ohms per mile to ohms per kilometer, multiply by 0.621371.

Example: 10.15 Ω/mi × 0.621371 = 6.30692 Ω/km.

In the other direction, 1 Ω/km = 1.60934 Ω/mi.
