Fundamental Formulas for Millivolts (mV) to Volts Conversion
Converting millivolts to volts is a straightforward process based on the metric system’s decimal scaling. The core formula is:
Where:
- Voltage (V) – The voltage value in volts, the SI unit of electric potential.
- Millivoltage (mV) – The voltage value in millivolts, where 1 mV = 0.001 V.
Alternatively, the formula can be expressed as a multiplication by the conversion factor:
This conversion factor (0.001) is derived from the metric prefix “milli,” which denotes one-thousandth (10⁻³) of the base unit.
Additional Related Formulas
- Volts to Millivolts: Millivoltage (mV) = Voltage (V) × 1000
- Microvolts (µV) to Volts: Voltage (V) = Microvoltage (µV) ÷ 1,000,000

Understanding these formulas is essential for accurate voltage measurement and conversion in electronic circuits and instrumentation.
Detailed Real-World Examples of Millivolts to Volts Conversion
Example 1: Sensor Output Voltage Conversion
A temperature sensor outputs a voltage of 250 mV corresponding to a specific temperature. To interface with a microcontroller ADC that requires voltage in volts, convert the sensor output.
- Given: Millivoltage (mV) = 250 mV
