Using Necessary Functions to Convert Milliseconds to Time in Excel

Formula Breakdown:

  • =TEXT(INT(B5/1000)/86400,”hh:mm:ss”):
    Divides the value in cell B5 by 1000 and subsequently by 86400, then converts the integer result into text format in “hours:minutes:seconds” format.
    Result: 12:44:32
  • =B5-(INT(B5/1000)*1000):
    Divides cell B5‘s value by 1000 and converts it into an integer, then multiplies the result by 1000 and subtracts it from the value of cell B5.
    Result: 0
  • =CONCATENATE(TEXT(INT(B5/1000)/86400,”hh:mm:ss”),”.”,B5-(INT(B5/1000)*1000)):
    Combines the first result with a decimal point (.) and joins it with the second result.
    Result: 12:44:32.0
  • Place your cursor on the bottom right position of the C5 cell.
