How to convert 45 minutes to decimal
Decimal hours = minutes ÷ 60, so 45 ÷ 60 = 0.75.
Going back: 0.75 × 60 = 45 minutes. Any whole number of hours plus 45 minutes ends in .75: 1:45 = 1.75, 7:45 = 7.75, 8:45 = 8.75.
Payroll example
You work 4 hours 45 minutes at $16.50 an hour.
- Convert the time: 4 + 45 ÷ 60 = 4 + 0.75 = 4.75 hours.
- Multiply by the rate: 4.75 × $16.50 = $78.38.
Typing 4:45 as 4.45 would pay $73.43 instead: $4.95 too little. Add up a whole week of clock times with the time card calculator.
