A century is exactly 100 years. The word derives from the Latin centuria. Centuries are used to mark major historical epochs, technological eras, and civilizational change.
Centuries define the way historians organize the past: the Industrial Revolution spans roughly the 18th–19th centuries; the Information Age began in the late 20th century. The Gregorian calendar's leap year rules operate on a 400-year cycle.
Interesting fact: The oldest verified living person (Jeanne Calment, France) lived 122 years — over a full century. Bristlecone pine trees live for over 50 centuries.
The nanosecond (one billionth of a second) became a practical unit with the rise of digital electronics in the 1960s. Early computer clock cycles were measured in microseconds; modern processors operate at speeds where individual cycles last less than one nanosecond.
Nanoseconds define the speed of modern computing: a 3 GHz processor completes one clock cycle in about 0.33 ns. RAM access latency is typically 50-100 ns; light travels about 30 cm in one nanosecond.
Interesting fact: Grace Hopper, the pioneering computer scientist, famously used a 30 cm wire to demonstrate what a nanosecond 'looks like' — the distance light travels in that time.
Converting century to nanosecond is a common task across science, engineering, and everyday planning. The time scale spans from nanoseconds in computing to centuries in history, and having accurate conversions helps when comparing measurements across different systems or disciplines.
As a quick reference: 5 cent = 1.5779e19 ns and 10 cent = 3.1558e19 ns. For the reverse: 1 ns = 3.1688e-19 cent. The exact conversion factor is 1 cent = 3.1558e18 ns.
All conversions are performed in IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
