Convert Attovolts to Nanovolts
Convert Attovolts (aV) to Nanovolts (nV) instantly and accurately.
Conversion Formula
nV = aV × 1.000000000e-9
About Attovolts
The attovolt (aV) equals 10⁻¹⁸ V, representing the tiniest detectable voltage signals in quantum electronics. SQUID (Superconducting Quantum Interference Device) magnetometers in flux-locked-loop mode achieve sub-attovolt-equivalent noise floors; theoretical calculations of vacuum fluctuations in nanoscale Josephson junctions reference the attovolt range. 1 aV = 10⁻00b3 fV = 10⁻¹⁸ V.
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.
