Which unit abbreviation denotes a voltage equal to one thousandth of a volt?

Explanation:
Understanding SI prefixes helps you read voltage values quickly. A prefix milli- indicates 10^-3, so a millivolt equals 0.001 volt. Therefore the unit used for a voltage about one thousandth of a volt is the millivolt, abbreviated mV. Other options use different prefixes: micro- is 10^-6 (microvolts, μV), nano- is 10^-9 (nanovolts, nV), and the volt is the base unit (1 V).
