Convert Ohms to Megohms
Enter the number of ohms that you want to convert to megohms.
How to Convert Ohms to Megohms
The ohm and megohm are both units of electrical resistance. By definition, 1 megohm equals exactly 1000000 ohms. This means to convert ohms to megohms, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 Ω to megohms:
We need to convert ohms to megohms
Since 1 MΩ = 1000000 Ω, divide by 1000000
5 ÷ 1000000 = 5e-6
5 Ω = 5e-6 MΩ

About These Units
Ohm (Ω)
The ohm (Ω) is the SI unit of electrical resistance. Named after Georg Simon Ohm. Defined by Ohm's Law: R = V/I (resistance = voltage ÷ current). Common resistor values: 10Ω to 10MΩ. Human body resistance: 1,000-100,000Ω depending on conditions.
Megohm (MΩ)
A megohm (MΩ) equals 1,000,000 ohms or 1,000 kilohms. Used for insulation resistance testing (should be >1 MΩ), high-impedance circuits, input resistance of oscilloscopes (1-10 MΩ), and anti-static resistors.
