microvolts to millivolts | Exact Decimal + Formula

1 Microvolt = 0.001 Millivolt

One millivolt equals exactly a thousand microvolts. Real-world use: radio-antenna signal levels and sensitive instrumentation. This page expresses those values in millivolts, which is used for sensor signals, ecg readings, and electronic circuit design. Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.

About Microvolt and Millivolt

Microvolt (µV)

µV to mV Formula and Examples

Direct Formula mV = µV × 0.001

Inverse Formula µV = mV × 1000

Mental Math Shortcut

Divide the value by roughly 1000 to quickly estimate the converted result.

Common Microvolt to Millivolt Calculations

5 µV = 0.005 mV
10 µV = 0.01 mV
50 µV = 0.05 mV
100 µV = 0.1 mV
500 µV = 0.5 mV

Precision & Practical Use

For example, 10 µV = 0.01 mV — roughly fractional unit measurement.

Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most electric voltage applications, 2–3 significant figures are plenty.

How to Convert Microvolt to Millivolt

How many millivolts are in one microvolt?

One Microvolt (µV) equals 0.001 Millivolt (mV). To convert microvolts to millivolts, multiply the microvolt value by 0.001.

How do I convert Microvolt to Millivolt?

Multiply your microvolt value by 0.001 to get the result in Millivolt: mV = µV × 0.001. For example, 5 µV = 0.005 mV.

What is the formula for converting µV to mV?

The conversion formula is mV = µV × 0.001. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
