About Milliohm (mΩ)
Metric submultiple of electrical resistance equal to one thousandth of an ohm (10⁻³ Ω).
History: Standard unit for high-current current sensing and contact resistance.
Common Uses: Current-sense shunt resistors, battery internal resistance, and PCB trace resistance.
About Ohm (Ω)
The SI unit of electrical resistance, defined as the electrical resistance between two points of a conductor when a constant potential difference of one volt applied between these points produces in the conductor a current of one ampere (1 Ω = 1 V/A).
History: Named after German physicist Georg Simon Ohm, who published Ohm’s law in 1827.
Common Uses: Standard measure of resistor components, circuit impedance, and wire resistance.
❓ Frequently Asked Questions
How many Ohms are in 1 Milliohm?
There are exactly 0.001 Ohms in 1 Milliohm (1 mΩ = 0.001 Ω).
What is the formula to convert Milliohm to Ohm?
The formula is: Ohm = Milliohm / 1000. Since 1 Ohm = 1000 Milliohms, divide the value in Milliohms by 1000.
How do I convert 1 mΩ to Ω manually?
To convert 1 mΩ to Ω: apply the formula Ohm = Milliohm / 1000. Substituting gives: 1 / 1000 = 0.001 Ω.
