Frequently asked questions
How do I convert millivolts to volts?
To convert millivolts to volts, multiply the value by 0.001: V = mV × 0.001. For example 12 mV = 0.012 V.
What is 1 mV in volts?
1 mV = 0.001 V. The other way round, 1 V = 1,000 mV.
How exact is the result?
The converter uses the official definitions of both units and shows up to 10 significant digits; choose 0–6 decimals to round. Both units are defined exactly in terms of each other, so the factor itself is exact.
Can I convert other units of voltage here?
