How long is 600 seconds
600 seconds lasts 10 minutes, with no leftover seconds. Write 10 min, 00:10:00 as elapsed time, or PT10M. Those labels are one span.
how long is 600 seconds
How long is 600 seconds is divide-by-sixty with a remainder of zero. Sixty seconds make one minute, so 600 ÷ 60 = 10. There is nothing left to carry as extra seconds. 10 minutes is 10/60 of an hour, which is 1/6 h. As decimal hours that is 0.1̅6 h, not 0.10 h and not 0.600 h. 0.10 hours is 6 minutes. 0.600 hours is 36 minutes. The digits 600 are allowed to look heavy. The unit is still seconds.
Neighbours on the same ladder stay in step: 60 seconds is 1 minute, 300 seconds is 5 minutes, 600 seconds is 10, 900 seconds is 15, 1,200 seconds is 20. The operation does not change when the remainder happens to be zero. That zero is why 600 feels round, and why it is easy to file next to 6:00 on a wall clock. 6:00 as a time of day is six o’clock. 6:00 as h:mm elapsed is six hours, which is 21,600 seconds, thirty-six times this span.
A kitchen timer, a classroom break, and a parking rule that say 600 seconds are all ten minutes. A log that says 600 with no unit is not. Look at the header. If the header is milliseconds, 600 ms is 0.6 seconds. If the header is microseconds, 600 µs is smaller still. How long is 600 seconds does not borrow those smaller units just because the digits match. 600 s = 10 min exactly 600 s = 1/6 h 600 s = 600,000 ms 540 s = 9 min 660 s = 11 min
10:00, 00:10:00, and the hour fraction
10:00 as mm:ss elapsed is ten minutes, which is 600 seconds, when the last field is seconds. 10:00 as hh:mm elapsed is ten hours. 00:10:00 as hh:mm:ss elapsed is ten minutes again. 00:10 as mm:ss is ten seconds, sixty times too short. Pad zeros only to show fields. Padding does not add time. Stripping zeros does not remove time. Field names do the work.
ISO 8601 duration form writes 600 seconds as PT600S or as PT10M. PT10M is easier to read. PT600S is harder to confuse with ten hours (PT10H). PT0.1667H is a rounded decimal hour; 1/6 is exact. Some parsers reject a fraction on H. Prefer PT10M or PT600S when a machine has to parse the span.
Six hundred seconds is ten minutes that has not yet asked the wall clock for a colon. The colon is punctuation. It is not a tenth minute. Payroll sheets that want decimal hours should store 1/6 or 0.1667 h for this span, not 10, not 600, and not 0.10. A cell formatted as duration may accept 0:10 and mean ten minutes. A cell formatted as a number will treat 0:10 as a time of day or reject it. Match the cell to the format, then type.
Questions and answers
- How many minutes is 600 seconds?
- 10 minutes exactly. 600 ÷ 60 = 10, remainder 0.
- Is 10:00 always 600 seconds?
- Only when 10:00 is ten minutes of elapsed time with seconds as the last field, or 00:10:00 as hh:mm:ss. As a clock stamp, 10:00 is ten o’clock.
- Is 600 milliseconds ten minutes?
- No. 600 milliseconds is 0.6 seconds. 600 seconds is 600,000 milliseconds.

100 seconds
100 seconds equals one minute forty seconds, or 100 s, or PT1M40S. It is a short duration. It is not 1:00, and it is not a hundred on a digital clock.
120 minutes in hour
120 minutes is 2 hours, because one hour holds 60 minutes. Write it as 2:00 or as two hours; it is not 120 hours.
13 hour cast
A 13 hour cast writes thirteen hours as a label in front of the word cast. Most people who type it want the actors in the film 13 Hours. The number is a duration, not a clock time.
