How to convert HOURS to DECIMAL

Two hours and 45 minutes equals 2.75 decimal hours because 45 minutes is three-quarters of an hour. Converting to decimal hours is a daily task for anyone billing by the hour or tracking work time.
Enter your time in hours and minutes and the converter calculates the decimal equivalent. The formula divides the minutes by 60 and adds the result to the hours. For example, 1 hour 30 minutes becomes 1 + 30/60 = 1.5 hours.
