How do you convert µV to mV?

To convert µV to mV, divide by 1,000. For example, 750 µV = 0.75 mV.

Is the µV to mV conversion exact?

Yes. Milli is 10⁻³ and micro is 10⁻⁶, so the conversion factor is exactly 1,000. There is no rounding or approximation involved.

Is micro bigger or smaller than milli?

Micro (10⁻⁶) is 1,000 times smaller than milli (10⁻³). One milli unit equals 1,000 micro units. So for voltage: 1 mV = 1,000 µV.

Example

750 µV = 0.75 mV

microvolt to millivolt formula

Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every µV to mV conversion uses the exact factor 1,000.

mV = µV ÷ 1,000
750 µV ÷ 1,000 = 0.75 mV

Understanding microvolts and millivolts

A microvolt (µV) is 10⁻⁶ of the base unit (volt) and a millivolt (mV) is 10⁻³. They sit three powers of ten apart, so going from µV to mV means dividing by exactly 1,000 — move the decimal point three places to the left.

Microvolts are where biopotentials and instrumentation noise live: EEG signals run 10–100 µV, ECG a few hundred, and a good instrumentation amplifier contributes only a few µV of input-referred noise. At this scale thermoelectric EMF at a solder joint is a real error source, not a rounding detail.

This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 750 µV returns exactly 0.75 mV — not a value with a trailing rounding error.

Common µV to mV mistake

Noise specs are often quoted as µV/√Hz (spectral density), not µV. Multiplying a density figure by 1000 to reach mV without first integrating over the measurement bandwidth produces a number that means nothing.

When to use µV vs mV

microvolts and millivolts are used for sensor output, bioelectric signals, audio noise floors, and precision instrumentation. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
