Convert Femtovolts to Abvolts
Convert Femtovolts (fV) to Abvolts (abV) instantly and accurately.
Conversion Formula
abV = fV × 1.000000000e-7
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 Abvolts
The abvolt (abV) equals exactly 10⁻⁸ V - the electric potential unit of the CGS-EMU (electromagnetic) system, defined as 1 erg per abcoulomb (= 10⁻⁷ J / 10 C). One abvolt per centimetre is the corresponding electric field unit (abV/cm). The abvolt appears in nineteenth- and early-twentieth-century electromagnetic engineering texts and in nuclear physics tables where CGS-EMU units are retained. 1 abV = 10⁻⁸ V = 10 nV.
