Formula
Step-by-Step Example
Convert 5 ms to seconds:
We need to convert milliseconds to seconds
Since 1 s = 1000 ms, divide by 1000
5 ÷ 1000 = 0.005
5 ms = 0.005 s

About These Units
Millisecond (ms)
A millisecond (ms) is one thousandth of a second. Milliseconds measure reaction times (human average: 250 ms), sports timing, video frame rates (33 ms per frame at 30fps), and internet ping times. A blink of an eye takes about 300-400 milliseconds.
Second (s)
The second (s or sec) is the SI base unit of time, defined by cesium-133 atomic transitions. Seconds measure pulse rate (60-100 per minute), athletic performance, cooking times, and countless daily activities. There are 60 seconds in a minute, 3,600 in an hour, 86,400 in a day.
