About this tool

Volt (V) is a unit of voltage (SI). Millivolt (mV) is a unit of voltage (SI); 1 mV = 0.001 V.

To convert volts to millivolts, multiply the value by 1,000 (mV = V × 1,000). Example: 12 V = 12,000 mV.

Frequently asked questions

How do I convert volts to millivolts?

To convert volts to millivolts, multiply the value by 1,000: mV = V × 1,000. For example 12 V = 12,000 mV.

What is 1 V in millivolts?

1 V = 1,000 mV. The other way round, 1 mV = 0.001 V.

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?

Yes – choose any of the 6 units of voltage in the From and To lists, or switch to another measurement at the top.
