Convert Femtovolts to Attovolts
Convert Femtovolts (fV) to Attovolts (aV) instantly and accurately.
Conversion Formula
aV = fV × 1000
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 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.
