How to Convert Years to Decades

Calendars document the days in a month

To convert a year measurement to a decade measurement, multiply the time by the conversion ratio. One year is equal to 0.1 decades, so use this simple formula to convert:

decades = years × 0.1

The time in decades is equal to the years multiplied by 0.1.

For example, here's how to convert 5 years to decades using the formula above.
5 yr = (5 × 0.1) = 0.5 decades

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

Years

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.

Years can be abbreviated as yr, and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y.

Decades

The decade is a time period of 10 years.
