Centuries (c.) to Decades (dec) Conversion
Centuries
The century is a unit of time equal to exactly 100 years, derived from the Latin centum (hundred). It is the standard unit for describing periods in historiography, architectural styles, and long-term scientific trends. The Julian century of 36,525 days is used in astronomy for expressing Earth's axial precession and stellar proper motion.
Decades
The decade is a unit of time equal to exactly ten years, derived from the Greek deka (ten). While not a formal SI unit, it is widely used in demography, economics, history, and popular culture. In science, decade-scale processes are important in climatology (decadal temperature averages), epidemiology (ten-year cohort studies), and astrophysics (stellar variability cycles).
