Conversion Formula
µcy = as × 3.168808781e-22
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 Microcenturies
A microcentury (µcy) = 10⁻⁶ of a Julian century = 3,155.76 s ≈ 52 min 35.76 s. Popularised by Richard Feynman, who told audiences a one-hour lecture was 'approximately one microcentury'. An 87-minute film ≈ 1.65 microcenturies. No formal SI recognition, but a favourite pedagogical example of SI prefixes applied to large bases. 1 µcy = 3,155.76 s = 52.596 min.
