Then there's the second moment of area, a quantity used in the design of beams 
and trusses. Typical values for beams are on the order of a million quartic 
millimeters or a millionth of a quartic meter. I think that unit should have 
a special name, even though only civil and structural engineers would use it.

I've seen a calculation which resulted in a fifth power of a length, but it 
was only an intermediate result.
