How the formula works
Both millivolt and volt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millivolts by 0.001 to get volts. To reverse the conversion, multiply a volt value by 1000 to get back to millivolts.
Frequently asked questions
What is Millivolt (mV)?
A millivolt (mV) equals one-thousandth of a volt and is common in sensor and biomedical signal measurements.
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
How do I convert millivolts to volts?
Multiply the millivolt value by 0.001 to get the equivalent in volts. For example, 5 mV × 0.001 = 0.005 V.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.001 is an exact, non-rounded value.
Can I convert volts back to millivolts?
Yes. Divide the volt value by 0.001, or multiply it by 1000, to get millivolts.
