To convert milliseconds (ms) to seconds (s), we use the fact that 1 millisecond is equal to 0.001 seconds.
Given:
531 milliseconds (ms)
To find how many seconds this equals, we divide the number of milliseconds by 1000 (since there are 1000 milliseconds in a second):
[tex]\[
531 \, \text{ms} = 531 \times 0.001 \, \text{s}
\][/tex]
So:
[tex]\[
531 \, \text{ms} = 0.531 \, \text{s}
\][/tex]
Therefore, 531 milliseconds is equal to 0.531 seconds.
