Convert Century to Second

The word "century" comes from the Latin word "centuria", meaning a group of 100. The concept of dividing time into centuries has roots in the Roman system of organizing time and military units. The idea of measuring time in centuries became more formalized during the Middle Ages, as historians began to structure history into manageable periods for recording and analysis. By the time of the Gregorian calendar, the century became a standard way to refer to a 100-year span, often used to discuss developments in history, such as "the 19th century" or "the 21st century." The century is now a common unit used in various fields like history, economics, and demographics.

The second has its origins in ancient Babylonian astronomy, where the day was divided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds. The concept of dividing time into smaller units became more standardized over time, particularly in the 17th century, when the development of more accurate clocks led to a need for precise measurements of time. The modern definition, based on the cesium-133 atom, was adopted in 1967 by the International System of Units (SI) to ensure consistency and precision in timekeeping across scientific fields. The second is now universally used as the fundamental unit of time.
