Years to Centuries Converter (yr to c.)

Years

The year is based on Earth's orbital period around the Sun. The Julian year used in astronomy is exactly 365.25 days (31,557,600 seconds). The Gregorian calendar approximates the tropical year as 365.2425 days through its leap year rule, achieving accuracy to within 26 seconds per year. In geology, time spans are expressed in millions of years (Ma) or billions of years (Ga).

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.
