To convert numbers to time in seconds in Excel, use the formula =A1*86400, where A1 contains your time value. Excel stores time as fractions of a day, so multiplying by 86,400 (the number of seconds in a day) converts your time value into seconds. Remember to format the cell where you're entering the formula to General or Number to view it as a standard number, rather than Excel's default time format.

FAQs & Answers

  1. What is the formula to convert time to seconds in Excel? Use the formula =A1*86400, where A1 contains your time value, because Excel stores time as fractions of a day and there are 86,400 seconds in a day.
