Convert Years to Milliseconds

1 yr = 31557600000 ms

1 yr = 31557600000 ms

years (yr) milliseconds (ms)
0.5 15778800000
1 31557600000
2 63115200000
5 157788000000
10 315576000000
25 788940000000
50 1.5779e+12
100 3.1558e+12
250 7.8894e+12
500 1.5779e+13
1000 3.1558e+13

To convert years to milliseconds, multiply the value by the conversion factor:

1 yr = 31557600000 ms

For example: 10 yr = 315576000000 ms

The Conversion Formula

To convert years to milliseconds, multiply the value by the conversion factor: 1 yr = 31557600000 ms. For a worked example, suppose you need to convert 25 yr to milliseconds: 25 × 31557600000 = 788940000000 ms. To convert in the opposite direction, divide by 31557600000, or equivalently multiply by 3.1688e-11.

About years

A year is the time it takes Earth to orbit the Sun. Because this orbit takes about 365.2425 days, we use leap years to keep our calendars synchronized with the seasons. In science, the 'Julian year' of exactly 365.25 days is the standard for defining units like the light-year. years are commonly used in Age, History, Mortgages (30-year), and Election cycles, Wine vintages.

It takes one year for Earth to orbit the Sun.

About milliseconds

The millisecond (ms) is the standard unit for measuring short duration events in computing and electronics. It is imperceptible to the human conscious mind, but critical for technology. A 'ping' of 100ms in a video game feels laggy, while 20ms feels instant. milliseconds are commonly used in Ping/Latency in gaming, Camera shutter speeds, Audio synchronization, and Reaction time testing, Computer clock cycles.

A blink of an eye takes 300-400 milliseconds.

When Would You Convert years to milliseconds?

Converting between years and milliseconds is one of the most common time conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 yr = 31557600000 ms) memorized or bookmarked can save time in professional and everyday contexts alike.
