Convert millivolts to microvolts and microvolts to millivolts instantly. Bidirectional voltage converter with formula and common values.

mV

Microvolts

3,300

µV

3.3 mV = 3,300 µV

µV = mV × 1000

Millivolts to Microvolts: 1 mV equals 1000 µV. To convert millivolts to microvolts, multiply by 1000 (µV = mV × 1000). For example, 10 mV = 10000 µV.

How to Convert Millivolts to Microvolts

To convert from millivolts to microvolts, multiply the value by 1000. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Millivolts to Microvolts: µV = mV × 1000
  • Microvolts to Millivolts: mV = µV ÷ 1000

Understanding the Units

What is a Millivolt?

The volt is the SI derived unit of electric potential difference, equal to one joule per coulomb (1 V = 1 J/C = 1 W/A).

Named after Alessandro Volta (1745–1827), Italian physicist who invented the first electrical battery.

Common contexts: power systems, electronics, batteries.

FAQ

How many microvolts are in one millivolt?

One millivolt equals exactly 1,000 microvolts (µV). The step from milli- to micro- is always a factor of 1,000.

How do I convert millivolts to microvolts?

Multiply the voltage in millivolts by 1,000. For example, 3.3 mV × 1,000 = 3,300 µV.

When would I use microvolts instead of millivolts?

Microvolts are used for EEG brain signals (5-100 µV), EMG muscle signals, and very low-level sensor outputs where millivolt precision is insufficient.

What is the relationship between µV, mV, and V?

One volt equals 1,000 millivolts or 1,000,000 microvolts. One millivolt equals 1,000 microvolts.

How many microvolts are in 1 millivolt?

1 mV equals 1000 µV.

How do you convert millivolts to microvolts?

Multiply the millivolt value by 1000. Formula: µV = mV × 1000.

How many microvolts are in 5 millivolts?

5 mV = 5000 µV.

How do you convert microvolts back to millivolts?

Use the inverse formula: mV = µV ÷ 1000. For example, 1 µV = 0.001 mV.

What is the difference between Millivolt and Microvolt?

The volt is the SI derived unit of electric potential difference, equal to one joule per coulomb (1 V = 1 J/C = 1 W/A). The volt is the SI derived unit of electric potential difference, equal to one joule per coulomb (1 V = 1 J/C = 1 W/A).
