## How Much Is a Decade?

The decade is a time period of 10 years.

To convert decades to another unit of time, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for decades in the conversion table below.

Then, multiply the time measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

decades × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
