Convert Femtovolts to Volts
Convert Femtovolts (fV) to Volts (V) instantly and accurately.
Conversion Formula
V = fV × 1.000000000e-15
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 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.
