How Decimal Hours Work for Payroll & Billing
In professional billing, timesheets, and legal accounting, time is commonly represented in decimal hours rather than sexagesimal (base-60) minutes.
To convert minutes to decimal hours, divide the minutes by 60:
| Minutes | Fraction | Decimal Equivalent |
|---|---|---|
| 15 minutes | 15 / 60 | 0.25 hours |
| 30 minutes | 30 / 60 | 0.50 hours |
| 45 minutes | 45 / 60 | 0.75 hours |
| 6 minutes (1/10th hr) | 6 / 60 | 0.10 hours |
