How this calculator works
One minute is defined as exactly 60 seconds. Multiplying a decimal minute value by 60 gives total seconds; dividing total seconds by 60 reverses the conversion. Decimal minutes describe a fraction of a minute, rather than digits on a clock.
Formula
seconds = minutes x 60; minutes = seconds / 60.
Worked example
A 2.75 minute interval is 165 seconds, or 2 minutes 45 seconds. A 45 second interval is 0.75 minutes.
