Millivolt is 0.001 volt units.
Millivolts to Nanovolts Converter — mV to nV
Convert Millivolt (mV) to Nanovolt (nV) using the exact conversion factor (1 millivolt = 1,000,000 nanovolt). See the formula, worked examples, and conversion table.

Electricity Converter
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.
Nanovolt is 1e-9 volt units.
Result = input x 0.001 / 1e-9.
Electrical units in the same family convert directly.

About Converting Millivolts to Nanovolts
Millivolt and Nanovolt 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 nanovolt is 1e-9 volt units.
Formula
nanovolts = millivolts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 millivolt equals 0.001 base units, and 1 nanovolt equals 1e-9 base units, so dividing one by the other gives the direct millivolt-to-nanovolt factor of 1000000.
Simple example
1 mV × 1000000 = 1,000,000 nV
1 millivolt = 1,000,000 nanovolts.
Real-world example
120 mV × 1000000 = 120,000,000 nV
120 millivolts = 120,000,000 nanovolts.

Reverse conversion: Nanovolt to Millivolt
1 nV × 0.000001 = 0.000001 mV
1 nanovolt = 0.000001 millivolts.
millivolts = nanovolts × 0.000001

Frequently asked questions
How many nanovolts are in 1 millivolt?
1 millivolt equals 1,000,000 nanovolts, using the exact defined conversion factor rather than an estimate.
How do I convert millivolt to nanovolt?
Multiply the millivolt value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert nanovolt back to millivolt?
Use the reverse factor: 1 nanovolt equals 0.000001 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 nanovolt?
Nanovolt (nV) is a unit of electricity.
Is the millivolt to nanovolt conversion exact?
Yes. Both millivolt and nanovolt are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
