Convert Yoctoseconds to Attoseconds
Convert Yoctoseconds (ys) to Attoseconds (as) instantly and accurately.
Conversion Formula
as = ys × 1.000000000e-6
About Yoctoseconds
A yoctosecond (ys) = 10⁻²⁴ s - the smallest named SI prefix time unit. Light travels ~0.3 fm in 1 ys, about one-tenth the proton charge radius. Strong-force quark binding operates on ~1 ys timescales; W and Z boson lifetimes are ~260-290 ys. Lead-lead collisions at the LHC produce quark-gluon plasma that thermalises within a few ys. These timescales are inferred from decay widths via ΔE × Δt ≥ ℏ. 1 ys = 10⁻²⁴ s.
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.
