To convert minutes in decimal format to a proper Excel time, just divide by 1440. For example, if you have a number that represents minutes in cell A1, use: If A1 contains the number 360 (representing 360 minutes) then the result will be 360/1440 = .25, since 360 minutes = 6 hours = 1/4 day.To see the result formatted in a normal time format, you'll need to change the number format to a time format.or example, if you have a number that represents minutes in cell A1, use: If A1 contains the number 360 (representing 360 minutes) then the result will be 360/1440 = .25, since 360 minutes = 6 hours = 1/4 day.

A quarter of an hour also means 0.25 hours, therefore, to convert this into minutes and seconds, simply multiply by 60 to get the minutes, and multiply the minutes by 60 again to get the seconds: 0.25 x 60 = 15 minutes. 15 x 60 = 900 seconds. You can also get your kids to practice convert the units backwards by simply dividing the value by 60. Learning to convert between hours, minutes, and seconds can also help your kids practice their multiplication and division skills.
