To convert a measurement in months to a measurement in decades, divide the time by the following conversion ratio: 120 months/decade.

Since one decade is equal to 120 months, you can use this simple formula to convert:

decades = months ÷ 120

The time in decades is equal to the time in months divided by 120.

For example, here's how to convert 500 months to decades using the formula above.
decades = (500 mo ÷ 120) = 4.166667 decades
