Convert Attoseconds to Decades
Convert Attoseconds (as) to Decades (dec) instantly and accurately.
Conversion Formula
dec = as × 3.168873851e-27
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 Decades
A decade = exactly 10 Gregorian years = 315,569,520 s. Climate scientists compute 10-year running means to remove interannual variability; IPCC reports compare decadal temperature anomalies. Moore's Law predicted ~10× transistor density increase per decade. US Census counts are constitutionally mandated each decade. Cultural periods are colloquially labelled by decade (the 1960s, the 1980s). 1 decade = 10 yr.
