Difference between 9am and 6pm

How many hours between 9am and 6pm?

Answer

The difference between 9am and 6pm is

9 Hours

= 540 Minutes · 9 decimal hours

9:00 AM → 6:00 PM the same day · by the clock, breaks not subtracted

With a 30-min unpaid break: 9 h − 30 min = 8 h 30 min paid

9:00 AM — start 6:00 PM — end

6:00 PM − 9:00 AM = 9 hours
