How to convert hours and minutes to decimal hours
Divide the minutes by 60 and add that value to the whole hours. For example, 45 minutes is 0.75 of an hour, so 7 hours 45 minutes becomes 7.75 decimal hours.
Time → decimal hoursHours + (minutes ÷ 60)

Why decimal hours are used on timesheets
Decimal hours are convenient when hours are multiplied by an hourly rate. For example, 7.50 hours at $20 per hour equals $150 before taxes, deductions or other payroll rules. Decimal time does not mean the same thing as clock minutes: 7.30 decimal hours is 7 hours 18 minutes, not 7 hours 30 minutes.
