About the units

Millisecond (ms)

One thousandth of a second. Network latency and reaction times are measured in milliseconds. One millisecond equals 0.001 seconds (s).

Year (yr)

The mean Gregorian calendar year of 365.2425 days, which accounts for leap years. One year equals 31,556,952 seconds (s).

Frequently asked questions

How many years are in one millisecond?

There are 3.168873851×10⁻¹¹ years in one millisecond, and this value is exact by definition.

How do I convert milliseconds to years?

Multiply the number of milliseconds by 3.168873851×10⁻¹¹. For example, 10 ms × 3.168873851×10⁻¹¹ = 3.168873851×10⁻¹⁰ yr.

How many milliseconds are in one year?
