How to convert kilohms to ohms
Reading resistor colour codes and schematics where values are given in kΩ.
To convert kilohms to ohms, use Ω = kΩ × 1000. One kilohm equals 1,000 ohms, and one ohm equals 0.001 kilohms.
Kilohm (kΩ): 1,000 Ω. Ohm (Ω): 1 V/A, the SI unit of resistance.
For the opposite direction, use the Ohms to kilohms 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 ohms are in a kilohm?
1 kΩ = 1,000 Ω. Multiply kilohms by 1000 (or use Ω = kΩ × 1000).
How do I convert kilohms to ohms?
Use Ω = kΩ × 1000. For example, 1 kΩ = 1,000 Ω and 10 kΩ = 10,000 Ω.
What does 4k7 mean?
4.7 kΩ — the “k” replaces the decimal point to avoid misreading a faint dot.
