The millivolt is a small voltage unit equal to one thousandth of a volt, used for low-level electrical signals.
It became essential in electronics and medical instrumentation for expressing precise, low-voltage readings.
Measurement system: International System of Units (SI, subunit). SI equivalent: 1 mV = 0.001 V.
