I would assume the question should read: how many microseconds in a second. mili second is 10-3 or 1000 milliseconds in a second. micro second is 10-6, or 1,000,000 micro seconds in a second.

In the metric system, how many milliseconds are needed to make one second?
One trillion. (10^-12) 1,000,000,000,000
a Milli-second = 1/1000 of a second. There are 1000 milli-seconds in 1 second, and86,400,000 ms = 24Hrs604,800,000 = 7 days.
864,000 seconds.
1,000 milliseconds make one seconds.
The question does not make sense. It needs to be reworded.
60 seconds actually make 1 minute.
This question doesn't make a lot of sense. Maybe something is missing? To convert seconds to metres per second you would need to divide the metres given by the number of seconds used. If all you have is seconds, and no distance, then you are stuck. Metres per second is a measure of speed and seconds is a measure of time. Speed=distance/time. So divide your metres by your seconds to get metres per second.
