MΩ to Ω Converter

Convert megaohms (MΩ) to ohms (Ω) and back, with the same value in other electrical resistance units.

What this tool does

Convert megaohms (MΩ) to ohms (Ω) and back, with the same value in other electrical resistance units. Type an amount in megaohms, choose the units, and the tool converts it to ohms. 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 Megaohm.
  • To: Choose one of the same 9 units as "From". Starts as Ohm.

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 megaohms to ohms:

  • 1 MΩ = 1,000,000 Ω
  • 5 MΩ = 5,000,000 Ω
  • 10 MΩ = 10,000,000 Ω
  • 50 MΩ = 50,000,000 Ω
  • 100 MΩ = 100,000,000 Ω

Multiply the number of megaohms by 1,000,000 to get ohms. Both units are exact definitions, so 1,000,000 is the exact factor: 1 MΩ = 1,000,000 Ω.

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 megaohms to other resistance units?
A: Type the value, pick megaohm 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 megaohm as the To unit and any other resistance unit as the From unit.
