How to Convert Decades to Years

Calendars document the days in a month

To convert a decade measurement to a year measurement, multiply the time by the conversion ratio. One decade is equal to 10 years, so use this simple formula to convert:

years = decades × 10

The time in years is equal to the decades multiplied by 10.

For example, here's how to convert 5 decades to years using the formula above.
5 decades = (5 × 10) = 50 yr
