Entering 10:30 could be a clock time or it could be a number of hours, Calc has no way to know and both are stored as the same numeric value you have keep track of what the value represents and make sure that the formatting is appropriate. It sometimes gets it right, but in reality, only the user knows for sure what the numeric value represents. Multiplying by 60 turns it into proper minutes (. The minutes remainder is a number less than 1, which represents a base 10 fraction of an hour (.25 15 minutes). ![]() The doubly confusing part is that Calc can only guess whether a value is a time or date or just another number. Ah, I do that to be safe with Double to Integer conversion, never sure if it rounds or drops the decimal. In the Format Cells dialog box: Change the Decimal places to 0. Enter a positive decimal number and choose the unit in days, hours, minutes or seconds. It looks like I could use DateDiff to return total minutes, however I want to use the date format in another spot (so I would use 7:30 on a label on the form and return back 7.5 to Sharepoint from my form). This date is the product of two different time picker boxes. When using payroll software, like Payentry, you must first convert minutes to decimals. Im trying to convert a time value to a decimal value, i.e. This will open the Format Cells dialog box. Use this simple Minutes to Decimals Conversion Chart to easily identify the correct decimal value for each unit of payroll time, a necessary step when processing payroll. Click the Format Cells dialog box launcher from the Number group. Multiply a fraction of a day by 24 and you get hours as a plain decimal number. To resolve this problem, use the following steps: Select the cell range affected by the issue. If you use the cell in a calculation, you get the decimal value, a fraction of a day. You import 10:30 and Calc converts that to 10.5 hours, divided by 24 hours in one day, or 7/16, and stores it as 0.4375, but displays it as 10:30. ![]() If you do a calculation on the value, Calc uses the stored numeric value, not the numbers you see on the screen. ![]() Calc stores a number of days as a plain integer numeric value, say 41340, but it displays it as when the cell is formatted as a date. What you see on the screen is not what is stored in the cells in many situations, what you see on the screen is very, very different from what is stored in the cell. How to convert numbers that represent time in hours from numeric to HMS format. The key thing to understand-and this is something that most spreadsheet users miss-is that a spreadsheet does not display what it stores. There is no magic at all: Calc stores all dates as a number of days after some fixed date, and all times as a (decimal) fraction of a day. I see that the *24 trick works, but I don't really understand it: I guess that time is interpreted essentially as a fraction, and when I multiply it times 24 it works off that interpretation AND it converts it to a normal number.
