millivolts to microvolts | Exact Decimal + Formula

1 Millivolt = 1000 Microvolt

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

mV to µV Formula and Examples

Direct Formula µV = mV × 1000

Inverse Formula mV = µV × 0.001

Mental Math Shortcut

Multiply the value by roughly 1000 to calculate the equivalent amount in your head.

Common Millivolt to Microvolt Calculations

5 mV = 5000 µV
10 mV = 10000 µV
50 mV = 50000 µV
100 mV = 100000 µV
500 mV = 500000 µV

Precision & Practical Use

For example, 10 mV = 10000 µV — roughly multiple unit increments.

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 Millivolt to Microvolt

How many microvolts are in one millivolt?

One Millivolt (mV) equals 1000 Microvolt (µV). To convert millivolts to microvolts, multiply the millivolt value by 1000.

How do I convert Millivolt to Microvolt?

Multiply your millivolt value by 1000 to get the result in Microvolt: µV = mV × 1000. For example, 5 mV = 5000 µV.

What is the formula for converting mV to µV?

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