Not at all unusual. I think it's now agin the law to sell "cuttable"
of stuff in imperial measurements. If anyone asks for something in inches,
I don't think they're even allowed to offer a conversion, or to cut it
to that length even if they have a suitable rule. My interpretation of the
law, that is, and it's probably wrong.
However, they are allowed to sell stuff in imperial when the measurement
is descriptive, rather than numerically-defining. The usual example given
is "a 12-inch pizza" and that's OK. When the controling dimension is
defined in imperial (like when it comes from the factory, and is not
to be "cut"), I think they HAVE to describe it as such.
So, it's not unusual to see wood sold as e.g. "2 inch * 4 inch * 2.4meter"
It's illegal (apparently) to display public road signs in metric (or "metric
but illegal to display massable products for e.g. potatoes in anything but
Figure that one out.
