Frequently Asked Questions
How do you convert minutes to decimal hours?
Divide the minutes by 60 to get the decimal fraction. For example: 30 minutes ÷ 60 = 0.5, so 7 hours 30 minutes = 7.5 decimal hours. For 45 minutes: 45 ÷ 60 = 0.75, so 3 hours 45 minutes = 3.75 decimal hours. This is the format used by most payroll systems and billing software.
Why use decimal hours for timesheets?
Decimal hours make arithmetic simple — you can add, subtract, and multiply directly. For example, multiplying 7.5 hours by your $20/hour rate gives $150. Working with hours:minutes would require converting first. Most modern payroll software stores time in decimal format. Billing at 6-minute (0.1 hour) increments is common in legal and consulting.
