Centuries to Microseconds (c to µs)

1 century equals 3.1556952×10¹⁵ microseconds exactly.

1 century = 3.1556952×10¹⁵ microseconds

How to convert centuries to microseconds

To convert centuries to microseconds, multiply the number of centuries by 3.1556952×10¹⁵. This factor is exact. To go the other way, multiply microseconds by 3.168873851×10⁻¹⁶ (rounded).

microseconds = centuries × 3.1556952×10¹⁵

Example: 10 centuries = 3.1556952×10¹⁶ microseconds.

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.

About these units

Century (c)

CalendarCurrent unit

One hundred years.

From Latin centum, a hundred, century has meant a hundred of many things. For time it became popular as a way to speak about a span longer than a lifetime can easily contain, and some languages organise history around it: Italian uses terms like Quattrocento for the 15th century, and Swedish writes 1900-talet for the years 1900 to 1999. Whether such a century starts at year 00 or year 01 is an old argument.

A century is 100 years, which here means 100 average Gregorian years. The strict view counts from year 1, because the AD calendar has no year zero, so the 1st century AD ran from AD 1 to AD 100 and the 21st century covers 2001 to 2100. The popular view groups years by their hundreds digit, making the 20th century 1900 to 1999. The Gregorian calendar itself treats century years specially, since 1700, 1800 and 1900 were not leap years while 1600 and 2000 were.

1 century = 3,155,695,200 seconds (exactly).

Microsecond (µs)

Metric (SI)Current unit

One millionth of a second. Used for electronics and processor timing.

Writing a microsecond takes a Greek letter, mu, which stands for the prefix micro-, one millionth. Where plain text cannot display it, people fall back on the letter u and write us. The unit belongs to electronics and radio: a signal that repeats every microsecond has a frequency of 1 MHz, and a radio wave of that period is about 300 m long.

A microsecond is one millionth of a second, short enough that light in a vacuum crosses only about 1 km in 3.34 of them. Digital audio lives on this scale, because a CD sample at 44.1 kHz lasts about 22.7 microseconds and a 48 kHz sample about 20.8. A modern solid-state drive has an access latency of about 50 microseconds, and a camera flash lasts around 1,000. Relativity matters at this scale too: GPS satellite clocks would drift by about 38 microseconds per day without compensation. Wikipedia notes that the 2011 Japanese earthquake shortened the day by about 1.8 microseconds.

1 microsecond = 0.000001 seconds (exactly).
