Convert Microohms to Milliohms

Convert microohms to milliohms by entering a value below.

1 μΩ (microohms) = 0.001(milliohms)

How to Convert Microohms to Milliohms

The microohm and milliohm are both units of electrical resistance. By definition, 1 milliohm equals exactly 1000 microohms. This means to convert microohms to milliohms, you divide by 1000.

Formula

milliohms = microohms ÷ 1000

Step-by-Step Example

Convert 5 μΩ to milliohms:

1
Convert 5 μΩ to milliohms

We need to convert microohms to milliohms

2
Apply the formula

Since 1 mΩ = 1000 μΩ, divide by 1000

5 ÷ 1000 = 0.005

Answer

5 μΩ = 0.005 mΩ

About These Units

Microohm (μΩ)

A microohm (μΩ) equals 10⁻⁶ ohms. Measures contact resistance, relay contacts, switch contacts, solder joints, and near-superconducting materials. Copper wire: ~17 μΩ·cm resistivity. Requires precision 4-wire Kelvin measurement.

Milliohm (mΩ)

A milliohm (mΩ) equals 0.001 ohms. Used for current sense resistors (1-100 mΩ), PCB trace resistance, wire resistance, battery internal resistance (5-50 mΩ), and contact resistance. Measurement requires 4-wire technique for accuracy.
