How to Convert Decades to Years
Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications.
To convert a measurement in decades to a measurement in years, multiply the time by the following conversion ratio: 10 years/decade.
Since one decade is equal to 10 years, you can use this simple formula to convert:
years = decades × 10
The time in years is equal to the time in decades multiplied by 10.
How Many Years Are in a Decade?
There are 10 years in a decade, which is why we use this value in the formula above.
1 decades = 10 yr
Decades and years 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.
