nanovolt

Voltageexact by definition

The nanovolt is one billionth of a volt. It is the unit of low-noise amplifier specification, where input noise is quoted in nanovolts per root hertz, and of the residual offsets in precision DC measurement. The factor of 1e-9 is exact, being an SI prefix.

Watch out: A copper to solder joint generates roughly 300 nanovolts per degree of temperature difference, so a warm hand near a terminal block is a measurable signal at this scale.
