I like the general rule "Spell out numbers of less than two digits" -- and I
include significant digits (expressed or implied). So if I am writing about
a measurement where I might have had to say 1.01 cubic inches I use numerals
-- even if the measurement actually turned out to be 1.00 cubic inches,
which some would express as a one-cubic-inch.
So even though some would express a measured quanity as "one cubic inch" I
stick to 1.00 (or even 1 cubic inch) because I feel that (as a reader) when
I see "one cubic inch" I think that's a nominal value ... like the
proverbial "give them an inch."
It's not the issue of the trailing units with me -- it's the precision. I'm
perfectly happy writing "2 hours" *and* "two hours" depending on what I
mean. "2 hours" means 2.0 hours (measured); two hours is what I use in
sentences like "it takes about two hours" ....
