- Scientific Notation
- 5 × 10⁰ mΩ
- Real-World Context
- 1 µΩ is roughly the high-current shunt resistor
- Step-by-Step
- 1. Start with 5,000 µΩ. 2. Since 1 micro-unit = 1/1,000th of a milli-unit, divide by 1,000. 3. 5,000 ÷ 1,000 = 5 mΩ.
- Formula Used
- ÷ 1,000 (micro = 10⁻⁶, milli = 10⁻³)

microohm to milliohm formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every µΩ to mΩ conversion uses the exact factor 1,000.
mΩ = µΩ ÷ 1,000
5,000 µΩ ÷ 1,000 = 5 mΩµΩ to mΩ table

Understanding microohms and milliohms
A microohm (µΩ) is 10⁻⁶ of the base unit (ohm) and a milliohm (mΩ) is 10⁻³. They sit three powers of ten apart, so going from µΩ to mΩ means dividing by exactly 1,000 — move the decimal point three places to the left.
Microohms cover weld and crimp integrity, superconducting joints and bulk-metal resistance standards. Measuring at this level requires four-wire Kelvin sensing — at 10 µΩ, ordinary test-lead resistance is a thousand times larger than the thing being measured.
This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 5,000 µΩ returns exactly 5 mΩ — not a value with a trailing rounding error.
Common µΩ to mΩ mistake
Two-wire measurement is the failure mode here. Typical lead and contact resistance of 10–100 mΩ swamps any mΩ or µΩ reading, so a two-wire meter reports its own leads no matter how carefully the units convert.
When to use µΩ vs mΩ
microohms and milliohms 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.
