That's a bad example, because you use exactly one hour.
If you divide the day in 10, let's call it decile, you would say see you in a decile instead of 2.43 hours.
As a side effect, 2.43h is actually 2h and less than 30 minutes and not 2h and 43 minutes (unintuitive), while 0.41 decile would probably be 41 centile, so conversion would be easier.
