Convert Megayears to Femtoseconds
Convert Megayears (Ma) to Femtoseconds (fs) instantly and accurately.
Conversion Formula
fs = Ma × 3.155695200e+28
About Megayears
A megayear (1 Ma) = 10⁶ yr ≈ 3.156 × 10¹³ s - the timescale of geology and tectonic evolution. The K-Pg mass extinction at 66.0 Ma; Cambrian explosion ~538.8 Ma; Great Oxygenation Event ~2,400 Ma. Plate motion at 2-10 cm/yr = 200-1,000 km per Ma (Atlantic ~3,000 km wider since Pangaea rifting ~200 Ma ago). Background extinction rate measured in extinctions per million species-years. 1 Ma = 10⁶ yr.
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.
