Convert Attoseconds to Nanoseconds
Convert Attoseconds (as) to Nanoseconds (ns) instantly and accurately.
Conversion Formula
ns = as × 1.000000000e-9
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 Nanoseconds
A nanosecond (ns) = 10⁻⁹ s; light travels ~30 cm - Grace Hopper distributed 30 cm wire segments as physical 'nanoseconds' to illustrate latency. CPU clock cycles at 3-5 GHz: 0.2-0.33 ns. DDR5 CAS latency ~10 ns. GPS requires <3 ns timing accuracy for sub-metre positioning. Lightning return strokes rise in 100-200 ns. Data-centre 400GbE switch latency 300-500 ns. 1 ns = 10⁻⁹ s.
