Weighted averages are used often in investing. It's basically how we measure the performance of our respective portfolios. In fact, the S&P 500 index is the weighted average performance of the 500 largest companies on the major U.S. stock exchanges by market capitalization.
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.

In Excel, time is stored as days, or fractions of a day. Since there are 24 hours in a day, 60 minutes in each hour, and 60 seconds in each minute, you need to divide by 24 * 60 * 60 = 86400 in order to convert decimal seconds to a value that Excel will recognize as time.Once you've done the conversion, you can apply a time format of your choice.o display hours that represent a duration longer than 24 hours, minutes in durations longer than 60 minutes, or seconds in durations over 60 seconds, you'll need to adjust the number format by adding square brackets. The brackets signal to Excel that the time is a duration, and not a time of day.
