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.
Millivolt is 0.001 volt units.
Result = input x 1e-6 / 0.001.

About Converting Microvolts to Millivolts
Microvolt and Millivolt 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: Microvolt is 0.000001 volt units, and millivolt is 0.001 volt units.
Formula
millivolts = microvolts × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 microvolt equals 0.000001 base units, and 1 millivolt equals 0.001 base units, so dividing one by the other gives the direct microvolt-to-millivolt factor of 0.001.
Simple example
1 uV × 0.001 = 0.001 mV
1 microvolt = 0.001 millivolts.
Real-world example
120 uV × 0.001 = 0.12 mV
120 microvolts = 0.12 millivolts.

Reverse conversion: Millivolt to Microvolt
0.001 mV × 1000 = 1 uV
0.001 millivolts = 1 microvolt.
microvolts = millivolts × 1000

Frequently asked questions
How many millivolts are in 1 microvolt?
1 microvolt equals 0.001 millivolts, using the exact defined conversion factor rather than an estimate.
How do I convert microvolt to millivolt?
Multiply the microvolt value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert millivolt back to microvolt?
Use the reverse factor: 1 millivolt equals 1,000 microvolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microvolt?
Microvolt (uV) is a unit of electricity.
What is a millivolt?
Millivolt (mV) is a unit of electricity.
Is the microvolt to millivolt conversion exact?
Yes. Both microvolt and millivolt are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
