How to Convert Years to Centuries

To convert a measurement in years to a measurement in centuries, divide the time by the following conversion ratio: 100 years/century.

Since one century is equal to 100 years, you can use this simple formula to convert:

centuries = years ÷ 100

The time in centuries is equal to the time in years divided by 100.

For example, here's how to convert 5 years to centuries using the formula above.

centuries = (5 yr ÷ 100) = 0.05 c

Years and centuries are both units used to measure time. Keep reading to learn more about each unit of measure.

What Is a Year?

One year is the time it takes for the Earth to complete its orbit around the Sun. There are 365 days in a year, with the exception of the leap year when there are 366.

We have leap years because the Earth actually takes 365.2425 days to revolve around the sun, but we round to 365 for convenience. However, since we miss a quarter of a day per revolution around the sun, this means that we add an extra day to the year once every 4 years, hence the leap year.

Years can be abbreviated as yr (plural yrs), and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y, and 2 years can be written as 2 yrs.

What Is a Century?

The century is a time period of 100 years. The word century is derived from the Latin word centum, meaning hundred.^[1]

Centuries can be abbreviated as c; for example, 1 century can be written as 1 c.
