Convert Millivolts to Femtovolts
Convert Millivolts (mV) to Femtovolts (fV) instantly and accurately.
Conversion Formula
fV = mV × 1000000000000
About Millivolts
The millivolt (mV) equals 10⁻³ V, the everyday scale of biomedical and electrochemical measurements. ECG R-wave peaks are 0.5-3 mV; a silicon p-n junction has a forward voltage of about 600 mV; pH electrodes produce roughly 59.2 mV per pH unit (Nernst equation at 25 °C); lithium-ion cells have an end-of-discharge cutoff at 2 700-3 000 mV. 1 mV = 10⁻³ V = 10³ µV.
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.
