Use this tool to convert any time period in months to years. You can enter whole numbers or decimal values, such as 6.5 months. The result will show the time in decimal years, for example 0.54 years. It will also show you the full year and the remaining months.
12 months = 1.0000 year
Equivalent Duration: 1 year
*Based on an average of 30.4375 days per month (365.25 days / 12 months).
To convert a duration from months into years, divide the number of months by 12 (since there are 12 months in one year).
Years = Months ÷ 12
For example, 18 months would be 18 ÷ 12 = 1.5 years.
The "Equivalent Duration" shown in the result breaks this down into full years and any remaining months.
Months % 12 or Months - (Full Years × 12).
