Time to Decimal Calculator
Payroll counts hours as decimals: 7 hours 45 minutes is 7.75 hours. Convert either way.
How to convert minutes to decimal hours
Divide the minutes by 60 and add the result to the whole hours.
Decimal hours = hours + minutes ÷ 60
7 hours 45 minutes: 45 ÷ 60 = 0.75, so 7.75 hours. To go back, multiply the part after the decimal point by 60: 0.4 × 60 = 24, so 8.4 hours is 8 hours 24 minutes.
Decimal hours make pay easy to work out: 7.75 hours at $18 is 7.75 × 18 = $139.50. Multiplying $18 by "7.45" would be wrong by $5.40.
