How to convert milliseconds to seconds
s = ms × 0.001
Example: 5 ms × 0.001 = 0.005 s

About these units
Milliseconds (ms): A millisecond is one thousandth of a second, used for reaction times, network latency and computing.
Seconds (s): The second is the SI base unit of time, defined by the caesium-133 atom’s radiation frequency.
Frequently asked questions
How many seconds are in 1 millisecond?
1 millisecond (ms) equals 0.001 seconds.
How do I convert ms to s?
Multiply the value in milliseconds by 0.001. For example, 5 ms × 0.001 = 0.005 s.
How do I convert seconds back to milliseconds?
Multiply by 1,000 (or divide by 0.001). 1 s = 1,000 ms.
What is a millisecond?
A millisecond is one thousandth of a second, used for reaction times, network latency and computing.
Conversion factors come from exact international definitions (NIST SP 811, BIPM) where they exist. Results show up to 10 significant digits. Need every time unit at once? Use the Time Converter.
