15 minutes = 0.25 hours; 30 minutes = 0.50 hours; 45 minutes = 0.75 hours; 60 minutes = 1.00 hour. These are quarter-hour increments that are easy to check mentally.
Do not write 15 minutes as .15 hours. A decimal fraction represents part of 60 minutes, not part of 100 minutes.
Use it in a timesheet
If your net shift is 7 hours 15 minutes, enter 7.25 when a decimal-hour field is required. If you have several shifts, convert each duration consistently or total the minutes first and convert the final duration.
