How to convert 38 minutes to decimal
Decimal hours = minutes ÷ 60, so 38 ÷ 60 = 0.6333…, which rounds to 0.63.
Going back: 0.63 × 60 = 37.8 minutes, which rounds to 38 minutes. Any whole number of hours plus 38 minutes ends in .63: 1:38 = 1.63, 7:38 = 7.63, 8:38 = 8.63.
Payroll example
You work 4 hours 38 minutes at $19.25 an hour.
- Convert the time: 4 + 38 ÷ 60 = 4 + 0.63 = 4.63 hours.
- Multiply by the rate: 4.63 × $19.25 = $89.13.
Paying on the exact time (4 hours 38 minutes × $19.25) gives $89.19. The $0.06 difference comes from rounding 4.6333… to 4.63.
Typing 4:38 as 4.38 would pay $84.32 instead: $4.81 too little. Add up a whole week of clock times with the time card calculator.
