Convert Ohms to Milliohms
Enter the number of ohms that you want to convert to milliohms.
How to Convert Ohms to Milliohms
The ohm and milliohm are both units of electrical resistance. By definition, 1 ohm equals exactly 1000 milliohms. This means to convert ohms to milliohms, you multiply by 1000.
Formula
Step-by-Step Example
Convert 5 Ω to milliohms:
We need to convert ohms to milliohms
Since 1 Ω = 1000 mΩ, multiply by 1000
5 × 1000 = 5000
5 Ω = 5000 mΩ

About These Units
Ohm (Ω)
The ohm (Ω) is the SI unit of electrical resistance. Named after Georg Simon Ohm. Defined by Ohm's Law: R = V/I (resistance = voltage ÷ current). Common resistor values: 10Ω to 10MΩ. Human body resistance: 1,000-100,000Ω depending on conditions.
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.
