This was a bit back but i received a response from a structural engineer
friend of mine and he tends to agree.

I would agree that designing steel in metric is not as user friendly.
The steel section properties are typically mm2, mm3 or mm4 and are
very
large numbers. For example the area of a W36x230 beam shape is 68 in2
or 43600 mm2. Similarly, the bending section modulus is 837 in3 or
13700000 mm3. The larger values are not that easy to work with.
Hope this helps.

What do you think of this? Is it really harder to design steel in
metric?

Sorry Howard, this has been sitting in my inbox.
