Convert Femtovolts (fV) to Nanovolts (nV) instantly and accurately.

Femtovolts (fV)
Nanovolts (nV)

Conversion Formula

nV = fV × 1.000000000e-6

About Femtovolts

The femtovolt (fV) equals 10⁻¹⁵ V, at the threshold of the most sensitive voltage amplifiers ever built. Cryogenic SQUID amplifiers for neutrino-mass experiments and dark-matter searches operate near 1 fV/√Hz noise levels; Josephson-voltage-standard arrays show thermal voltage noise of a few femtovolts at millikelvin temperatures. 1 fV = 10⁻00b3 pV = 10³ aV.

About Nanovolts

The nanovolt (nV) equals 10⁻⁹ V, the sensitivity scale of precision nanovoltmeters and cryogenic measurement chains. Type K thermocouples generate about 40 µV/°C, but at cryogenic temperatures the Seebeck coefficient drops to nanvolts per kelvin; lock-in amplifiers in MEMS research resolve signals of 1-10 nV. A modern 8.5-digit benchtop multimeter (e.g. Agilent 34420A) has a nanovolt resolution range. 1 nV = 10⁻00b3 µV = 10³ pV.
