A millisecond is equal to one thousandth of a second. So, 800 milliseconds is equal to 0.8 seconds.
To convert milliseconds to seconds, you can use the following formula:
seconds = milliseconds / 1000
In this case, the calculation would be:
seconds = 800 / 1000
seconds = 0.8
Here are some other examples of millisecond to second conversions:
1000 ms = 1 s 2000 ms = 2 s 3000 ms = 3 s ...
You can also use a online converter to convert milliseconds to seconds.
I hope this helps! Let me know if you have any other questions.
