How to Convert Milliohms to Ohms

conversion scale showing milliohms and equivalent ohms electrical resistance values

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

ohms = milliohms ÷ 1,000

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

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

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

Milliohms

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.

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.[1]

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.
