Convert Femtovolts to Kilovolts
Convert Femtovolts (fV) to Kilovolts (kV) instantly and accurately.
Conversion Formula
kV = fV × 1.000000000e-18
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 Kilovolts
The kilovolt (kV) equals 10³ V, used in high-voltage power supplies, X-ray machines, and electricity distribution. Dental and medical X-ray tubes operate at 60-120 kV; CRT television picture tubes required 20-30 kV for the final anode; distribution transformers step down from transmission lines at 11-33 kV to the local grid. Tesla coils generate sparks at tens to hundreds of kilovolts. 1 kV = 10³ V = 10⁻³ MV.
