Convert Femtovolts to Megavolts
Convert Femtovolts (fV) to Megavolts (MV) instantly and accurately.
Conversion Formula
MV = fV × 1.000000000e-21
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 Megavolts
The megavolt (MV) equals 10⁶ V, the scale of lightning and particle accelerator potentials. A typical cloud-to-ground lightning channel has a potential difference of 100-300 MV between cloud and ground; Van de Graaff generators in tandem accelerators reach 10-25 MV; ultra-high-voltage direct-current (UHVDC) transmission lines operate at 0.8-1.1 MV to carry bulk power thousands of kilometres with low losses. 1 MV = 10⁶ V = 10⁻³ GV.
