Millivolt Unit | All you need to know

A millivolt (mV) is a unit of electrical voltage equal to one thousandth of a volt (10^-3 volts). Millivolts are standard in biomedical applications, where electrocardiograms (ECGs) and electroencephalograms (EEGs) measure brain and heart electrical activity in millivolt ranges. Sensitive sensors and instrumentation use millivolt-level measurements. The unit is practical for low-voltage signal measurement and appears in laboratory and medical equipment specifications.
