## How to Convert Ohms to Milliohms

To convert a measurement in ohms to a measurement in milliohms, multiply the electrical resistance by the following conversion ratio: 1,000 milliohms/ohm.

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

The electrical resistance in milliohms is equal to the electrical resistance in ohms multiplied by 1,000.

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

### How Many Milliohms Are in an Ohm?

There are **1,000** milliohms in an ohm, which is why we use this value in the formula above.

1 Ω = 1,000 mΩ

Ohms and milliohms 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 Milliohm?

One milliohm is equal to 1/1,000 of an ohm. A milliohm is the resistance between two points of a conductor with an electrical potential difference of 1/1,000th of a volt with one ampere of current flowing through it.

The milliohm is a multiple of the ohm, which is the SI derived unit for electrical resistance. In the metric system, "milli" is the prefix for thousandths, or 10^{-3}. Milliohms can be abbreviated as *mΩ*; for example, 1 milliohm can be written as 1 mΩ.
