How to Convert Years to Months

Calendars document the days in a month

To convert a year measurement to a month measurement, multiply the time by the conversion ratio. One year is equal to 12 months, so use this simple formula to convert:

months = years × 12

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

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

Years and months are both units used to measure time. Keep reading to learn more about each unit of measure.


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.

Years can be abbreviated as yr, and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y.


One month is a unit of time equal to 1/12 of a year. The month is a unit of time used on a calendar, and ranges in length from 28 to 31 days.

Months can be abbreviated as mo, for example 1 month can be written as 1 mo.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
