Time calculations and the clock
How many hours did you work, with the break taken off? And what is 7 h 45 min as a decimal on the timesheet?
Your numbers
Answer
Total time
8 h 0 min
As a decimal
8t
In minutes
480min
How to work it out
- 115:45 − 07:15 = 8 h 30 min
- 2− 30 min break = 8 h 0 min
- 38 h 0 min = 8 t
The formula
1 t = 60 min · 1 døgn = 24 t
Time is counted in 60s and 24s, not in 10s.
0,25 t = 15 min · 0,5 t = 30 min · 0,75 t = 45 min
Timesheets are often written in decimals. 7 h 30 min is 7.5 h — not 7.3.
