Seconds to Milliseconds Converter
Converts seconds into milliseconds for timeouts, delays and animation settings in software.
1 s = 1,000 ms
milliseconds
1 s = 1,000 ms
How to convert seconds to milliseconds
Multiply the number of seconds by 1,000.
Formula
ms = s × 1,000
Examples
- 0.25 s × 1,000 = 250 ms
- 1.5 s × 1,000 = 1,500 ms
- 30 s × 1,000 = 30,000 ms

About seconds
The second is the SI base unit of time. It is defined by atomic physics: 9,192,631,770 oscillations of the radiation from a caesium-133 atom.
About milliseconds
A millisecond is one thousandth of a second. Computer response times, audio latency and reaction times are typically measured in milliseconds.
Frequently asked questions
How many milliseconds are in one second?
One second equals 1,000 milliseconds.
How do I convert seconds to milliseconds?
Multiply the number of seconds by 1,000. For example: 1.5 s × 1,000 = 1,500 ms.
How many seconds are in one millisecond?
One millisecond equals 0.001 seconds.
