Seconds to Milliseconds Converter

1 second (s) equals 1,000 milliseconds (ms).

Quick answer

  • 1 second = 1,000 milliseconds
  • 1 millisecond = 0.001 seconds
  • Formula: ms = s × 1,000

1 second = 1,000 milliseconds

How to convert seconds to milliseconds

ms = s × 1,000

To convert seconds to milliseconds, multiply the number of seconds by 1,000.

Example: 42 s to ms

  1. Start with the value in seconds: 42 s.
  2. Multiply by 1,000: 42 × 1,000 = 42,000.
  3. Result: 42 seconds = 42,000 milliseconds.

Going the other way, 1 millisecond = 0.001 seconds, so to convert milliseconds back to seconds you divide by the same number. See milliseconds to seconds.
