Convert Microseconds to Femtoseconds
Convert Microseconds (µs) to Femtoseconds (fs) instantly and accurately.
Conversion Formula
fs = µs × 1000000000
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 Femtoseconds
A femtosecond (fs) = 10⁻¹⁵ s - the timescale of molecular vibrations and chemical reactions. Bond stretching: 10-200 fs; bending: 50-500 fs. Ahmed Zewail won the 1999 Nobel Prize in Chemistry for femtochemistry, capturing transition states in real time. Ti:sapphire lasers produce 10-100 fs pulses; LASIK uses 10-100 fs for precise corneal cuts. At 800 nm, one optical cycle = 2.67 fs. Light travels 300 nm in 1 fs. 1 fs = 10⁻¹⁵ s.
