Accepts numbers or expressions, e.g. 150 + 14.7
Result
kΩ
Rendered to 6 significant figures.
Formula
Formula
kΩ = Ω × 0.001
Multiply any value in ohms by 0.001 to obtain the value in kilo-ohms.
Worked example
Convert 1000 Ω to kΩ.
- 01Start with 1000 Ω.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kΩ.
Result1000 Ω = 1 kΩ

FAQ
What is the conversion factor from Ω to kΩ?
1 Ω equals 0.001 kΩ. To convert, multiply the value in ohms by 0.001.
How do I convert 1 Ω to kΩ?
1 Ω = 0.001 kΩ. For any value, multiply by 0.001.
How do I convert kΩ back to Ω?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kΩ = 1000 Ω.
When would I need to convert ohm to kilo-ohm?
Resistance conversions between Ω and kΩ are used in electrical-network analysis, instrumentation (RTD/thermistor specification), grounding and bonding measurements, and electronics design. Ohms cover most circuit calculations; kΩ and MΩ appear in input-impedance specs, while milli-ohms cover bus-bar joints and shunt resistors.
Is the conversion exact?
Yes. Both Ω and kΩ are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
