How the Time Converter works
One second is exactly 0.0166666667 minutes. That is a fixed convention, not a measurement: 60 seconds to the minute, 60 minutes to the hour, 24 hours to the day and 7 days to the week, with the second as the SI base unit. Leap seconds adjust the clock against the Earth's rotation; they do not change the length of a minute or an hour as a unit, so this factor is exact.
Worked through: 100 s x 0.0166666667 = 1.66667 min.
Going the other way, one minute is 60 seconds.
For mental arithmetic: Divide by 6 and drop a zero. Or remember that 90 seconds is 1.5 minutes and scale.
Dividing by 60 rarely gives a whole number, and what you do with the remainder is the decision this conversion turns on. 100 seconds is 1.6667 minutes as a decimal and 1 minute 40 seconds as a clock reading, and those are different answers to different questions: the first goes in a spreadsheet, the second on a stopwatch. Video, audio and race times use the second form; anything that will be summed or averaged needs the first.
Precision is worth matching to the input. A measurement given as 30 s carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
