How to Convert Ohms to Milliohms

conversion scale showing ohms and equivalent milliohms electrical resistance values

To convert a ohm measurement to a milliohm measurement, multiply the electrical resistance by the conversion ratio. One ohm is equal to 1,000 milliohms, so use this simple formula to convert:

milliohms = ohms × 1,000

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

For example, here's how to convert 5 ohms to milliohms using the formula above.
5 Ω = (5 × 1,000) = 5,000 mΩ

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


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.


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


One milliohm is equal to 1/1,000 of an ohm, which is the resistance between two points of a conductor with one ampere of current at one volt.

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 10-3. Milliohms can be abbreviated as mΩ, for example 1 milliohm can be written as 1 mΩ.
