How to Convert Decimal Hours to Hours and Minutes

Converting decimal hours to hours and minutes is a simple two-step mathematical process. Whether you received a corporate payroll export in decimal format, tracked project hours, or computed timesheets in Excel — here is exactly how to find the equivalent in hours and minutes.

Standard Formula: Hours = whole number. Minutes = decimal fraction × 60.
Example: 7.75 decimal hours = 7 hours and 45 minutes (calculated as 0.75 × 60 = 45)

1
Identify the whole number (hours) The digits before the decimal point represent your hours.
For 7.75 → 7 hours.
For 2.33 → 2 hours.
2
Multiply the decimal part by 60 (minutes) Take only the remaining decimal fraction and multiply by 60.
For 7.75 → 0.75 × 60 = 45 minutes.
For 2.33 → 0.33 × 60 ≈ 20 minutes.
3
Combine for your answer Put them together.
7 hours + 45 minutes = 7 hours and 45 minutes (recorded as 7:45).
Hours = floor(decimal)  ·  Minutes = (decimal − floor) × 60 Example: 3.75 → floor(3.75) = 3h · (3.75−3) × 60 = 0.75 × 60 = 45m → 3 hours and 45 minutes
