# Milliseconds to Years Conversion

Enter the time in milliseconds below to get the value converted to years.

Results in Years: 1 ms = 3.1689E-11 yr
Hint: use a scientific notation calculator to convert E notation to decimal

## How to Convert Milliseconds to Years To convert a millisecond measurement to a year measurement, divide the time by the conversion ratio.

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

years = milliseconds ÷ 31,556,952,000

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

For example, here's how to convert 50,000,000,000 milliseconds to years using the formula above.
50,000,000,000 ms = (50,000,000,000 ÷ 31,556,952,000) = 1.584437 yr

## 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.

## 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.
