Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Microvolt is 0.000001 volt units.
Result = input x 0.001 / 1e-6.

About Converting Millivolts to Microvolts
Millivolt and Microvolt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Millivolt is 0.001 volt units, and microvolt is 0.000001 volt units.
Formula
microvolts = millivolts × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 millivolt equals 0.001 base units, and 1 microvolt equals 0.000001 base units, so dividing one by the other gives the direct millivolt-to-microvolt factor of 1000.
Simple example
1 mV × 1000 = 1,000 uV
1 millivolt = 1,000 microvolts.
Real-world example
120 mV × 1000 = 120,000 uV
120 millivolts = 120,000 microvolts.

Reverse conversion: Microvolt to Millivolt
1 uV × 0.001 = 0.001 mV
1 microvolt = 0.001 millivolts.
millivolts = microvolts × 0.001

Frequently asked questions
How many microvolts are in 1 millivolt?
1 millivolt equals 1,000 microvolts, using the exact defined conversion factor rather than an estimate.
How do I convert millivolt to microvolt?
Multiply the millivolt value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert microvolt back to millivolt?
Use the reverse factor: 1 microvolt equals 0.001 millivolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a millivolt?
Millivolt (mV) is a unit of electricity.
What is a microvolt?
Microvolt (uV) is a unit of electricity.
Is the millivolt to microvolt conversion exact?
Yes. Both millivolt and microvolt are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
