A standard year has 12 months. This count stays the same in both common years and leap years.
Divide the number of months by 12.
Example: 18 months ÷ 12 = 1.5 years.
Multiply the number of years by 12.
Example: 2.5 years × 12 = 30 months.
Yes. 24 months equals 2 years because 24 ÷ 12 = 2.
Yes. Half a year is 6 months because 12 months ÷ 2 = 6 months.
36 months is 3 years.
Math: 36 ÷ 12 = 3.
48 months is 4 years.
Math: 48 ÷ 12 = 4.
60 months is 5 years.
Math: 60 ÷ 12 = 5.
1.5 years is 18 months.
Math: 1.5 × 12 = 18.
0.75 years is 9 months.
Math: 0.75 × 12 = 9.
Not for a basic months-to-years conversion. Months vary from 28 to 31 days, but the month count in a year is always 12. If you need an exact time span in days, use days instead of months.
Divide by 12 to get years, then use the remainder as months.
Example: 29 months = 2 years and 5 months (since 24 months is 2 years, and 29 − 24 = 5).
10 years equals 120 months.
Math: 10 × 12 = 120.
20 years equals 240 months.
Math: 20 × 12 = 240.
Yes. A leap year has 12 months, just like any other year. The difference is one extra day in February.
That number is an average that accounts for leap years. It’s useful for long time spans in days, but it doesn’t change the rule that 1 year equals 12 months.
Use 12 months = 1 year. For quick estimates, remember common points:
