Frequently asked questions
How many mV are in one V?
1 V = 1,000 mV.
What is the formula to convert V to mV?
mV = V × 1,000. To go back, V = mV × 0.001.
Where are millivolts used?
Sensor outputs, thermocouples and signal levels are quoted in millivolts. The conversion to volts is a fixed factor and does not depend on the current.
