Convert Attovolts to Volts
Convert Attovolts (aV) to Volts (V) instantly and accurately.
Conversion Formula
V = aV × 1.000000000e-18
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 Volts
The volt (V) is the SI derived unit of electric potential, defined as 1 joule per coulomb (1 J/C = 1 W/A = 1 kg·m²·A⁻¹·s⁻³). Named after Alessandro Volta who built the first electrochemical battery in 1800. Common benchmarks: a fresh AA alkaline cell is 1.5 V; USB 2.0 supplies 5 V; a car lead-acid battery is 12 V; household electricity in Europe is 230 V RMS. The volt is reproduced internationally via the Josephson voltage standard.
