Convert Zeptoseconds to Attoseconds
Convert Zeptoseconds (zs) to Attoseconds (as) instantly and accurately.
Conversion Formula
as = zs × 0.001
About Zeptoseconds
A zeptosecond (zs) = 10⁻²¹ s. In 2020, physicists at Goethe University Frankfurt measured the H₂ photoionisation time at ~247 zs - the first direct event measurement at this timescale. W-boson lifetime ~300 zs; strong-force quark confinement dynamics ~1-3 zs. These timescales are resolved via the energy-time uncertainty relation and lattice-QCD simulations. 1 zs = 10⁻²¹ s = 1,000 ys.
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.
