mΩ to µΩ Converter
Convert milliohms (mΩ) to microohms (µΩ) instantly — just multiply by 1,000. Free tool with formula, worked examples, conversion table, and Ω base-unit equivalent.
Quick mΩ to µΩ answer
1 mΩ = 1,000 µΩ
multiply by 1,000
5 mΩ = 5,000 µΩ
milliohm to microohm formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mΩ to µΩ conversion uses the exact factor 1,000.
µΩ = mΩ × 1,000
5 mΩ × 1,000 = 5,000 µΩmΩ to µΩ table

Understanding milliohms and microohms
When dealing with resistance, accuracy is paramount. The difference between a milliohm (mΩ) and a microohm (µΩ) might seem small, but it represents a magnitude difference of one thousand. In scientific notation, a milliohm is expressed as 10⁻³, while a microohm is 10⁻⁶ of the base unit (ohm).
Converting from milliohms to microohms is a standard mathematical operation across various technical fields, as they are commonly used for PCB trace resistance, shunt resistors, contact resistance, cable resistance, and four-wire Kelvin measurement. The conversion is always an exact multiple of 1,000, meaning you simply move the decimal point three places to the right (when converting milli to micro) or three places to the left (when converting micro to milli).
Because the metric system is based on powers of ten, learning how to quickly translate mΩ into µΩ (or vice-versa) can save valuable time in laboratory environments, engineering calculations, and academic research. We designed this mΩ to µΩ calculator to perform this exact transformation without any floating-point errors, ensuring that whether you are working with 5 mΩ or much larger figures, your final microohm value is perfectly precise.
When to use mΩ vs µΩ
milliohms and microohms are used for PCB trace resistance, shunt resistors, contact resistance, cable resistance, and four-wire Kelvin measurement. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
