Convert hours and minutes to decimal hours
You worked for 2 hours and 45 minutes. A form asks for decimal hours. Enter 2.75, not 2.45: minutes are parts of 60, while decimal places are parts of 100.
The calculation
Decimal hours = whole hours + minutes ÷ 60. For 2 hours 45 minutes: 2 + 45 ÷ 60 = 2.75.
| Minutes | Decimal hours |
|---|---|
| 15 | 0.25 |
| 30 | 0.50 |
| 45 | 0.75 |
| 60 | 1.00 |
Convert decimal hours back to minutes
Keep the whole hours and multiply the decimal part by 60. For 2.75 hours: 0.75 × 60 = 45 minutes, so the result is 2 hours 45 minutes.
Example: subtract an unpaid break
From 08:00 to 16:00 is 8 hours. Subtract a one-hour unpaid break and you have 7 hours. At an example rate of €30 per hour, that gives €210. This example is a simple time-and-rate calculation.
See the calculation in TAS 4-in-One
The existing app demo adds 2 hours and 45 minutes, then switches the result to 2.75 decimal hours. The work-time demo also shows a break and an hourly rate.
