Conversion Formula
The basic formula to convert months to years is: Years = Months ÷ 12.
This works because one year always has 12 months. Dividing the number of months by 12 gives the equivalent number of years. For example, if you have 90 months:
- Start with 90 months.
- Divide 90 by 12.
- Calculate 90 ÷ 12 = 7.5.
- The result means 7 full years and 0.5 years, which is 6 months.
This formula turns a time period measured in months into years, by breaking the months into yearly chunks.
