I do... to me, 1 1/2 day == 36 hours, 2 days = 48, etc.

The only ambiguity I ever really notice is when talking in business terms.

For example, if a business says 10 day turnaround, they mean 10
business days, which is actually at least 12 calendar days, since
business days are only M - F.  But if I say I'll have something done
in 2 days, I mean 2 days, or 48 hours.
