Converting Time into Minutes using Excel

February 4, 2009

Something I’ve had many customers asking is how they can convert their time figures into minutes using a spreadsheet, it’s something that’s really easy to do if you know the correct formula to use.

I’m going assume that you’ve exported the data from our system so it’s in the format 1:30 (1 hour, 30 minutes), a good report to export is the Time Summary report (found on the Reports Page).

Converting your Time to Minutes

If you have 1:30 and you want it in minutes (90 Minutes) then create a new column alongside your time figures then enter the formula ={cell}*1440

You’ll need to make sure the cells are being formatted correctly, so select your “Time” column, right click and select “Format Cells” then make sure you’ve set the cell type to Custom h:mm

Then do the same for your “Minutes” column and make sure the cell type is set to Number with no decimals

You should end up with a nice list.

    I need to covert Hours to minutes. In the first column, A, I enter my Data as hours and minutes. The cells are formatted as [h]:mm. The second column, B, is formatted as Numbers with 2 decimal places. The formula for the column B cells are =hour(A1)*60+Minute(A1) I enter 23:46 in the first column cell and get 1426.00 minutes in Column B1. This is correct. This formula work great, until I input anything greater then 24 hours in the first column. For example: If I enter 30:45 in the A1 cell, when converted to minutes it should be 1845 minutes. Excel give 405.00 minutes in column B1 which is not correct even though the"A1" field is formatted to show hours greater than 24. How can I get the formula to work?

    Knowing the start time and end time of a person reporting to work each day is in a format of 7:15 (start) and 4:13 (finish) how do I determine the total minutes worked and convert that to hours and minutes.

      Hi Steve,

      Can you please email the question to include your company name and contact number.

      Also, is the 4:13 the same day? or PM?

    my cells are formatted 00:00 its formatted that way because i can enter just the numbers and get the time instead of adding the colon manually, now when i have this formatting i cant find a way to get my times into minutes because of this

    Great help…thank you, but if we wanted to sum the time and if comes in (- time) how do we use this formula…it does not work… appreciate if you could help on this.

  • Dopey

    How do we do it with 24 hour working time?
    For example
    start 23:00 finish 01:30 should equal 150 minutes.
    I am trying to simplify logs so i don't need to manually add the minutes.
    Would really appreciate some help with this one

  • Ivan

    Why don't u use =(HOUR(A2)*60)+(MINUTE(A2))+(SECOND(A2)/60) instead?

  • Seminko

  • Menino Fernandes

    Fantastic! Worked perfectly fine and saved me a lot of work which was done actually in Microsoft Word. Thank you very much. Regards – Menino

  • Ben

    When applying the formula ={cell}*1440 is there a way to format all cells in the column with the variable {cell}, or do I have to type it in for each cell calculation?
