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.

About Milliseconds

A millisecond (ms) = 10⁻³ s. Human visual reaction time 150-300 ms; auditory reaction 140-160 ms. Echo delays below ~30 ms cause Haas reinforcement; 100-500 ms are perceived as distinct echoes. One cinema frame at 24 fps = 41.7 ms; 60 fps gaming requires 16.7 ms/frame. Millisecond pulsars rotate in 1.4-30 ms. MIDI keyboard on-latency 1-3 ms. 1 ms = 10⁻³ s.
