How to convert ohms to kilohms
Resistor values are printed in ohms, kΩ (often just “k”, e.g. 4k7 = 4.7 kΩ) and MΩ.
To convert ohms to kilohms, use kΩ = Ω ÷ 1000. One ohm equals 0.001 kilohms, and one kilohm equals 1,000 ohms.
Ohm (Ω): 1 V/A, the SI unit of resistance. Kilohm (kΩ): 1,000 Ω.
For the opposite direction, use the Kilohms to ohms converter. All electrical resistance units are on the resistance converter.
Limitations
- Results are rounded to the decimal places you choose; the calculation itself keeps full precision.
Frequently asked questions
How many kilohms are in a ohm?
1 Ω = 0.001 kΩ. Multiply ohms by 0.001 (or use kΩ = Ω ÷ 1000).
How do I convert ohms to kilohms?
Use kΩ = Ω ÷ 1000. For example, 1 Ω = 0.001 kΩ and 10 Ω = 0.01 kΩ.
How many ohms are in a kilohm?
1,000 Ω.
What does 4k7 mean?
4.7 kΩ — the “k” replaces the decimal point to avoid misreading a faint dot.
