µs = t_P × 5.391247000e-38
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 Microseconds
A microsecond (µs) = 10⁻⁶ s; light travels ~300 m. Professional DSLR shutters reach 125 µs (1/8,000 s); electronic flash freezes motion in 1-50 µs. Radar pulse repetition intervals: 100-2,000 µs (15-300 km range). Ultrasound echo round-trips from 1-15 cm tissue depth: 13-200 µs. Muscle twitch contraction starts within 1-5 µs of the action potential. 1 µs = 10⁻⁶ s.
