How to convert 20 minutes to decimal
Decimal hours = minutes ÷ 60, so 20 ÷ 60 = 0.3333…, which rounds to 0.33.
Going back: 0.33 × 60 = 19.8 minutes, which rounds to 20 minutes. Any whole number of hours plus 20 minutes ends in .33: 1:20 = 1.33, 7:20 = 7.33, 8:20 = 8.33.
Payroll example
You work 6 hours 20 minutes at $24.00 an hour.
- Convert the time: 6 + 20 ÷ 60 = 6 + 0.33 = 6.33 hours.
- Multiply by the rate: 6.33 × $24.00 = $151.92.
Paying on the exact time (6 hours 20 minutes × $24.00) gives $152.00. The $0.08 difference comes from rounding 6.3333… to 6.33.
Typing 6:20 as 6.20 would pay $148.80 instead: $3.12 too little. Add up a whole week of clock times with the time card calculator.
