How the formula works
Both milliohm and ohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliohms by 0.001 to get ohms. To reverse the conversion, multiply a ohm value by 1000 to get back to milliohms.
Frequently asked questions
What is Milliohm (mΩ)?
A Milliohm (mΩ) equals 1/1,000 ohm(s), a scaled unit of electrical resistance used for milli-scale electrical work.
What is Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
How do I convert milliohms to ohms?
Multiply the milliohm value by 0.001 to get the equivalent in ohms. For example, 5 mΩ × 0.001 = 0.005 Ω.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert ohms back to milliohms?
Yes. Divide the ohm value by 0.001, or multiply it by 1000, to get milliohms.
