Isn't that what I said? Or are you saying that "cubic inches" is incorrect
and should instead be "cubic inch"?

No, I just shot first and read later :-)

Yes, that was what I was taught all those years ago 100 ft^2 = 10000 sq ft.

Remembering that I use imperial measures. One gallon of water was
defined as weighing 10 lb of water at STP (Standard Temperature and
Pressure).

Makes no sense to me; look:
u = 1 ft
100 u^2 = ?
With the power operation defined as binding stronger by convention,
that's obviously = 100 sq ft.

very common term the convention was to write 100 sq ft = 10 ft squared
or 10 ft ^2.
Just think that 16 oz = 1 lb but 1 pint = 20 fluid ounces. Unless you
are American then 1 pint = 16 fluid ounces.

In verbal conversation with non-engineers, who knows. In engineering notation,
no. I'm old enough to have had my co-op (intern) experience with a firm that
worked and thought exclusively in Imperial Units (I think back then they were so
arrogant as to call them Engineering Units). I was schooled exclusively in SI in
college. I think once I was asked to perform an engineering calculation, and
made a mistake when I insisted on converting to SI first and then back to
British. That one group didn't ask me again.

In a similar question, where you are, is "ten square meters" the same as
"ten meters square"?

I ordered stamps from Zazzle that read "Place Stamp Here".

Never heard of anyone using "ten meters square". Doesn't even make much
sense.

Sure it does. Ten square metres is an area of two metres by five metres,
an area ten metres square is ten by ten = 100 m^2
