How to Convert Years to Milliseconds

Calendars document the days in a month

To convert a year measurement to a millisecond measurement, multiply the time by the conversion ratio. One year is equal to 31,556,952,000 milliseconds, so use this simple formula to convert:

milliseconds = years × 31,556,952,000

The time in milliseconds is equal to the years multiplied by 31,556,952,000.

For example, here's how to convert 5 years to milliseconds using the formula above.
5 yr = (5 × 31,556,952,000) = 157,784,760,000 ms

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

Years

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.

Milliseconds

The millisecond is a multiple of the second, which is the SI base unit for time. In the metric system, "milli" is the prefix for 10-3. Milliseconds can be abbreviated as ms, for example 1 millisecond can be written as 1 ms.
