Er, no mixed it up (again! ;):
Yasim usess a mix of unit systems: pounds for mass, but metres for length=
s

So moment of inertia becomes "pounds per square metre", which doesn't mak=

anyone happy.

I'm quite sure my conversion to kg/m=B2 is correct (the values I get look=
s
sane), but numbers in pounds, slugs, gallons, feet etc are about as
meaningful to me as if they were given in "yellow striped hedgehogs per
square prostethnic waterfalls".

...think it should be divided by about ten rather than multiplied. ...?
