Decimal time questions, answered

How do I convert hours and minutes to decimal hours?

Divide the minutes by 60 and add the result to the whole hours. Example: 8 hours 45 minutes = 8 + 45/60 = 8.75 decimal hours. Payroll systems multiply decimal hours by the hourly rate.

What is 8 hours 30 minutes in decimal?

8.5 decimal hours. Common values: 15 minutes = 0.25, 30 minutes = 0.5, 45 minutes = 0.75.

How do I convert decimal hours back to hours and minutes?

The whole number is the hours; multiply the decimal part by 60 for the minutes. Example: 7.75 = 7 hours and 0.75 × 60 = 45 minutes.

Why does payroll use decimal hours instead of hours and minutes?

Pay is rate × time, and multiplication needs one unit. 8h 45m × $20 is awkward; 8.75 × $20 = $175.00 is one step. Timesheets record h:mm for people and convert to decimal for the math.
