1000 milliseconds = 1 second so 8 milliseconds = 8/1000 = 0.008 seconds. Simple!
8/1000 = 0.008 seconds
Since 1000 milliseconds = a second then 800 milliseconds is .8 seconds 1000/800
500 seconds, or 8 and 1/3 minutes
8 x 60 = 480
480 divide by 60 equals 8 8 minutes.
There are 60 seconds in one minute, so 480 seconds equals 8 minutes (60 x 8) and 510 seconds would equal 8.5 minutes or 8 minutes and 30 seconds, if you prefer.
Milliseconds are used when something is too quick to measure in seconds or where you need more accuracy to be able to differentiate two results. Say the 100 metre sprint for instance, at olympic level (in or around). Hypothetically say that all 8 runner's times were actually 9.6, 9.7, 9.9, 10.053, 10.2, 10.23, 10.45, 10.474. If all of these were rounded to just seconds they would all finish in 10 seconds and you would have 8 people in 1st place. Therefore having milliseconds, opr even a shorter time than seconds allows more precise and accurate values.
8 days = 691,200 seconds.
252288000 seconds in 8 years
There are 8 * 60 * 60 = 28800 seconds in 8 hours.
1 minute = 60 seconds. 8 minutes = 480 seconds
494 seconds.
