Ohm to Milliohm Converter

How many Milliohms are in 1 Ohm?

One Ohm equals 1000 Milliohms. You can also write this as 1 Ohm = 1000 Milliohms. Use the calculator to convert Ohm to Milliohm instantly.

Use this Ohm to Milliohm converter to change a value from Ohm into Milliohm. Enter the measurement, review the result, and use the conversion when comparing values or checking a formula.

This conversion is useful when a measurement is recorded in Ohm but a report, specification, or calculation requires Milliohm. The page includes the unit definitions, a worked example, and a conversion table for related units.

Use the result as a reference and check the displayed precision before copying it into technical or scientific work. The last digits may be rounded for readability.

Ohm and Milliohm describe the same electrical resistance measurement in different units. Converting between them makes values easier to compare when different unit systems are used.

How to convert Ohm to Milliohm (Ω to mΩ)

To convert Ohm to Milliohm, multiply by 1000. The formula is Ohm × 1000 = Milliohm. See the example below.

1 Ohm = 1 × 1000 = 1000 Milliohms

Ohm is a unit of measurement for electrical resistance. By definition, electrical resistance of a conductor is equal to one ohm when a constant potential difference of one volt applied between its ends produces in this conductor a current of one ampere. The symbol for Ohm is Ω.

Milliohm is a unit of measurement for electrical resistance. Milliohm is a decimal fraction of electrical resistance unit ohm. One milliohm is equal to 0.001 ohms. The symbol for Milliohm is mΩ.

How to Use Ohm to Milliohm Converter

Select Ohm from the first dropdown and enter the value you want to convert.
Choose Milliohm in the second dropdown to set the target unit.
Review the converted value in the output field.
Check the displayed precision before using the result in another calculation.

For another result, change the input value or either selected unit. The conversion uses the unit definitions in the calculator and formats the result for display.
