Convert Picovolts to Femtovolts
Convert Picovolts (pV) to Femtovolts (fV) instantly and accurately.
Conversion Formula
fV = pV × 1000
About Picovolts
The picovolt (pV) equals 10⁻¹² V, the realm of precision metrology and quantum voltage standards. The Josephson voltage standard used by national metrology institutes (NIST, PTB, NPL) reproduces the volt to within 0.01 pV using Cooper-pair tunnelling arrays driven by microwave radiation. Thermocouple noise in cryogenic circuits is also measured in picovolts. 1 pV = 10⁻00b3 nV = 10³ fV.
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.
