Formula
Formula
V = mV × 0.001
Multiply any value in millivolts by 0.001 to obtain the value in volts.
Worked example
Convert 5000 mV to V.
- 01Start with 5000 mV.
- 02Multiply by the conversion factor: 5000 × 0.001 = 5 V.
Result5000 mV = 5 V

FAQ
What is the conversion factor from mV to V?
1 mV equals 0.001 V. To convert, multiply the value in millivolts by 0.001.
How do I convert 1 mV to V?
1 mV = 0.001 V. For any value, multiply by 0.001.
How do I convert V back to mV?
Divide by the same factor — or equivalently, multiply by 1000. So 1 V = 1000 mV.
When would I need to convert millivolt to volt?
Voltage conversions between mV and V are routine in instrumentation, power-system analysis and electronics design. Volts and kilovolts dominate power-system documents (LV/MV/HV switchgear, motor ratings), while millivolts and microvolts appear on transducer datasheets, thermocouple signal chains and low-level analog measurements.
Is the conversion exact?
Yes. Both mV and V are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
