## How to Convert Ohms to Megaohms

To convert an ohm measurement to a megaohm measurement, divide the electrical resistance by the conversion ratio. One megaohm is equal to 1,000,000 ohms, so use this simple formula to convert:

megaohms = ohms ÷ 1,000,000

The electrical resistance in megaohms is equal to the ohms divided by 1,000,000.

For example, here's how to convert 5,000,000 ohms to megaohms using the formula above.
5,000,000 Ω = (5,000,000 ÷ 1,000,000) = 5 MΩ

## Ohms

The ohm is the resistance between two points of an electrical conductor transmitting a current of one ampere when the potential difference is one volt.

The ohm is the SI derived unit for electrical resistance in the metric system. Ohms can be abbreviated as ; for example, 1 ohm can be written as 1 Ω.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the resistance in ohms as an expression using current and voltage.

R = VVIA

The resistance in ohms is equal to the potential difference in volts divided by the current in amperes.

## Megaohms

One megaohm is equal to 1,000,000 ohms, which is the resistance between two points of a conductor with one ampere of current at one volt.

The megaohm is a multiple of the ohm, which is the SI derived unit for electrical resistance. In the metric system, "mega" is the prefix for 106. Megaohms can be abbreviated as MΩ; for example, 1 megaohm can be written as 1 MΩ.
