Conversion Formula

ns = t_P × 5.391247000e-35

About Planck Time

The Planck time (t_P) = √(ℏG/c⁵) ≈ 5.391 × 10⁻⁴⁴ s — the time for light to travel one Planck length (~1.616 × 10⁻³⁵ m). Below this scale, general relativity and quantum mechanics both break down; a theory of quantum gravity is needed. No physical process or instrument approaches this timescale — it is a theoretical lower bound. Introduced by Max Planck in 1899. 1 t_P ≈ 5.391 × 10⁻⁴⁴ s.

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.
