Electric Resistance Converter

Convert between electric resistance units: ohm (Ω), milliohm (mΩ), microohm (µΩ), kiloohm (kΩ), megaohm (MΩ) and more.

What this tool does

Convert between electric resistance units: ohm (Ω), milliohm (mΩ), microohm (µΩ), kiloohm (kΩ), megaohm (MΩ) and more. Type an amount in ohms, choose the units, and the tool converts it to kiloohms. It offers 9 electrical resistance units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 9 options, including Abohm (EMU of resistance), Nanoohm, Microohm, Milliohm, Ohm, Kiloohm. Starts as Ohm.
  • To: Choose one of the same 9 units as "From". Starts as Kiloohm.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from ohms to kiloohms:

  • 1 Ω = 0.001 kΩ
  • 5 Ω = 0.005 kΩ
  • 10 Ω = 0.01 kΩ
  • 50 Ω = 0.05 kΩ
  • 100 Ω = 0.1 kΩ

Multiply the number of ohms by 0.001 to get kiloohms. Both units are exact definitions, so 0.001 is the exact factor: 1 Ω = 0.001 kΩ.

Limitations

  • Converts the unit of a resistance only. It does not work out resistance from voltage, current, length or material.
  • Abohm and statohm are historical CGS units, listed for completeness.

FAQs

Q: How do I convert ohms to other resistance units?
A: Type the value, pick ohm as the From unit and any other resistance unit as the To unit. The page also lists the same value in every other unit at once.
Q: What are abohms and statohms?
A: They are resistance units from the older CGS electromagnetic and electrostatic systems. One abohm is exactly 1 nanoohm (10⁻⁹ ohm). One statohm is about 8.99 × 10¹¹ ohms.
Q: Can I convert the other way?
A: Yes. Choose ohm as the To unit and any other resistance unit as the From unit.
