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.

The simplest way to convert a time to a number of minutes is to multiply the time by 1440, which is equal to 24*60 (the number of minutes in one day): For the time 02:30:30, the formula in cell B2 of the above spreadsheet returns the value 150.5. I.e. 2 hours 30 minutes and 30 seconds is equal to 150.5 minutes. (The reason that this method works is because Excel times are internally stored as decimal values, with the value 1.0 used to represent 24 hours, and therefore, the value 1/1440 used to represent 1 minute).
