Convert Femtoseconds to Centuries
Convert Femtoseconds (fs) to Centuries (cent) instantly and accurately.
Conversion Formula
cent = fs × 3.168873851e-25
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.
About Centuries
A century = exactly 100 Gregorian years ≈ 3.156 × 10⁹ s. Standard unit of historical periodisation (the 20th century, the 18th-century Enlightenment). IPCC projects warming and sea-level rise on century timescales. Precession of the equinoxes advances ~1.39°/century, so zodiac constellations no longer match their named seasons. Ice-core and radiocarbon records are commonly displayed at century resolution. 1 century = 100 yr.
