How to Convert Years to Milliseconds

To convert a measurement in years to a measurement in milliseconds, multiply the time by the following conversion ratio: 31,556,952,000 milliseconds/year.

Since one year is equal to 31,556,952,000 milliseconds, you can use this simple formula to convert:

milliseconds = years × 31,556,952,000

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

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

How Many Milliseconds Are in a Year?

There are 31,556,952,000 milliseconds in a year, which is why we use this value in the formula above.

1 yr = 31,556,952,000 ms

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

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.

What Is a Millisecond?

One millisecond is equal to 1/1,000 of a second or 1,000 microseconds.

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 thousandths, or 10-3. Milliseconds can be abbreviated as ms; for example, 1 millisecond can be written as 1 ms.
