nanovolts
Minuscule electrical measurements
Nanovolts are units of electrical potential equal to one billionth of a volt.
The prefix nano- indicates 10⁻⁹, making nanovolts useful for measuring extremely small voltage differences in sensitive electronics, neuroscience, and precision instrumentation: The brain signals were measured in nanovolts.
