Convert millivolts to volts
1 mV = 0.001 V — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
0.001V
As a fraction: 1/1000
1 mV = 0.001 V
How to convert millivolts to volts
Multiply the number of millivolts by 0.001 to get volts.
The exact factor is 0.001 — as a fraction, 1/1000.
