How to convert ohms to kilohms
kΩ = Ω × 0.001Multiply the value in ohms by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
An ohm is smaller than a kilohm: it takes 1,000 ohms to make one kilohm.

About the units
Ohm (Ω)
One volt per ampere.
Kilohm (kΩ)
The kilohm (kΩ) is a unit of electric resistance in the International System of Units (SI). One kilohm equals 1,000 ohms (Ω).
Frequently asked questions
How many kilohms are in one ohm?
There are 0.001 kilohms in one ohm, and this value is exact by definition.
How do I convert ohms to kilohms?
Multiply the number of ohms by 0.001. For example, 10 Ω × 0.001 = 0.01 kΩ.
How many ohms are in one kilohm?
One kilohm equals 1,000 ohms. That is the reverse factor, 1 ÷ 0.001.
What is 10 ohms in kilohms?
10 Ω = 0.01 kΩ.
Is this Ω to kΩ converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
