Nanovolt is 1e-9 volt units.
Nanovolts to Millivolts Converter — nV to mV
Convert Nanovolt (nV) to Millivolt (mV) using the exact conversion factor (1 nanovolt = 0.000001 millivolt). 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.
Millivolt is 0.001 volt units.
Result = input x 1e-9 / 0.001.
Electrical units in the same family convert directly.

About Converting Nanovolts to Millivolts
Nanovolt 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: Nanovolt is 1e-9 volt units, and millivolt is 0.001 volt units.
Formula
millivolts = nanovolts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanovolt equals 1e-9 base units, and 1 millivolt equals 0.001 base units, so dividing one by the other gives the direct nanovolt-to-millivolt factor of 0.000001.
Simple example
1 nV × 0.000001 = 0.000001 mV
1 nanovolt = 0.000001 millivolts.
Real-world example
120 nV × 0.000001 = 0.00012 mV
120 nanovolts = 0.00012 millivolts.

Reverse conversion: Millivolt to Nanovolt
0.000001 mV × 1000000 = 1 nV
0.000001 millivolts = 1 nanovolt.
nanovolts = millivolts × 1000000

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