Difference between 9am and 10am

How many hours between 9am and 10am?

Answer

The difference between 9am and 10am is

1 Hour

= 60 Minutes · 1 decimal hour

9:00 AM → 10:00 AM the same day · by the clock, breaks not subtracted

With a 30-min unpaid break: 1 h − 30 min = 30 min paid

9:00 AM — start 10:00 AM — end

10:00 AM − 9:00 AM = 1 hour
