## How to Convert Ohms to Megaohms

To convert a measurement in ohms to a measurement in megaohms, divide the electrical resistance by the following conversion ratio: 1,000,000 ohms/megaohm.

Since one megaohm is equal to 1,000,000 ohms, you can use this simple formula to convert:

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

**For example,**here's how to convert 5,000,000 ohms to megaohms using the formula above.

Ohms and megaohms are both units used to measure electrical resistance. Keep reading to learn more about each unit of measure.

## What is an Ohm?

An ohm is the resistance between two points of an electrical conductor transmitting a current of one ampere when the electrical potential difference is one volt between the points.^{[1]}

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

### Ohm's Law

Ohm's Law states the current flowing between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. More specifically, the current is equal to the voltage divided by the resistance.

Using Ohm's Law, it's possible to express the resistance in ohms as an expression using current and voltage.

R_{Ω} = V_{V} / I_{A}

Here, the resistance *R* in ohms is equal to the potential difference *V* in volts divided by the current *I* in amperes.

## What is a Megaohm?

One megaohm is equal to 1,000,000 ohms. A megaohm is the resistance across a conductor with an electrical potential difference of 1,000,000 volts with one ampere of current flowing through it.

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 millions, or 10^{6}. Megaohms can be abbreviated as *MΩ*; for example, 1 megaohm can be written as 1 MΩ.
