Where the figures come from
This sum uses only the numbers you entered.
How it adds up time
- Each time is turned into minutes: hours × 60, plus the minutes.
- The minutes are added up, taking away any time marked with a minus.
- The total is turned back into hours and minutes: divide by 60 for the hours, and what is left is the minutes.
Decimal hours
Timesheets often want hours as a decimal. 7 hours 30 minutes is 7.5 hours, because 30 minutes is half an hour. 7 hours 45 minutes is 7.75 hours. To turn minutes into a decimal, divide them by 60.
