Convert Attoseconds to Picoseconds
Convert Attoseconds (as) to Picoseconds (ps) instantly and accurately.
Conversion Formula
ps = as × 1.000000000e-6
About Attoseconds
An attosecond (as) = 10⁻¹⁸ s - the timescale of electron dynamics in atoms. The Bohr-model orbital period in hydrogen is ~152 as. Electron tunnelling through atomic potential barriers takes a few hundred as. The 2023 Nobel Prize in Physics (Agostini, Krausz, L'Huillier) honoured methods for generating sub-100 as pulses via high-harmonic generation in Ti:sapphire lasers. 1 as = 10⁻¹⁸ s = 1,000 zs.
About Picoseconds
A picosecond (ps) = 10⁻¹² s; light travels 0.3 mm. Water molecules reorient via H-bond dynamics in ~1-3 ps, explaining microwave absorption. THz spectroscopy probes ps-scale dynamics in molecular systems. Sub-5 nm CMOS gate delays are a few ps; GaAs HEMTs reach ~0.1 ps. Muon mean lifetime = 2,197 ps. OTDR uses ps pulses for millimetre-resolution fibre-fault location. 1 ps = 10⁻¹² s.
