    formula hour-minute

    Hello everyone this formula:
    transform hours/cents in hours/minutes



    it does not work properly.
    If the hours are greater than 24, it is not correct
    I hope I explained.
    I am attaching the sample files.

    The formula

    =ORA(1/24*C8)+MINUTO(1/24*C8)/100+SECONDO(1/24*C8)/10000

    =HOUR(1/24*C8)+MINUTE(1/24*C8)/100+SECOND(1/24*C8)/10000

    Try

    =TEXT(A2/24,"[hh]:mm:ss")
    Life's a spreadsheet, Excel!

    Re: formula hour-minute

    I would suggest a review of how Excel stores dates and times: http://www.cpearson.com/Excel/datetime.htm#SerialDates

    Since time is simply "fraction of a day" convert the decimal hours to fraction of a day: =A2/24
    Format as elapsed time (not "time of day"). Format code like [h]:m:s https://support.office.com/en-us/art...2-09fab54be7f4

    Hello ace_xl
    your formula works, but it is not the correct:
    =SUM(C2:C7)
    perhaps not accept the format TEXT.

    =SUM(C2:C7) perhaps not accept the format TEXT.
    Correct, the SUM() function ignores text arguments, including "numbers stored as text". Ace_XL's formula returns a text string, so the sum function ignores results of the TEXT() function.

    Did you try my solution? Mine does the same thing, except it does not convert the values to a text string. It relies on number formatting to provide the sexagesimal notation we are used to.

    Hello MrShorty.
    I tried it and it works as you say.

    =A3/24
    size > Custom > [hh]:mm:ss

    Thank you.
    A greeting.
