Ohms per 1,000 feet to ohms per kilometer
Type a value in Ω/1000 ft to get it in Ω/km instantly.
33.3Ω/km
That's 4.5× as resistive as 2.5 mm² copper cable, while AWG 24 network wire is 2.5× more resistive. A 10 m run carrying 10 A loses 6.66 V there and back.
Convert the other way: Ω/km to Ω/1000 ft
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/1000 ft to Ω/km
To convert ohms per 1,000 feet to ohms per kilometer, multiply by 3.28084.
Example: 10.15 Ω/1000 ft × 3.28084 = 33.3005 Ω/km.
In the other direction, 1 Ω/km = 0.3048 Ω/1000 ft.
