How to Convert Years to Months

To convert a measurement in years to a measurement in months, multiply the time by the following conversion ratio: 12 months/year.

months = years × 12

The time in months is equal to the time in years multiplied by 12.

For example, here's how to convert 5 years to months using the formula above.
months = (5 yr × 12) = 60 mo

What Is a Year?

One year is the time it takes for the Earth to complete its orbit around the Sun. There are 365 days in a year, with the exception of the leap year when there are 366.

We have leap years because the Earth actually takes 365.2425 days to revolve around the sun, but we round to 365 for convenience. However, since we miss a quarter of a day per revolution around the sun, this means that we add an extra day to the year once every 4 years, hence the leap year.

Years can be abbreviated as yr (plural yrs), and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y, and 2 years can be written as 2 yrs.
