English is not my first language, but doesn't "pounds per square meter" mean lb/m² ? lb/m² could be interpreted as pressure. lb*m² is moment of inertia. > > I'm quite sure my conversion to kg/m² is correct (the values I get looks kg/m² could be pressure. > 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". Actually feet and inches are pretty meaningfull since you can use your limbs as reference. :-) > ...think it should be divided by about ten rather than multiplied. ...? I'm pretty sure what you had in your patch and what I wrote in my last post is correct. According to http://www.wsdot.wa.gov/reference/metrics/factors.htm 1 ft² = 0.09290304 m² => 1 m² = 1/0.09290304 ft² = 10.763910 ft² -- Roy Vegard Ovesen ------------------------------------------------------------------------- Take Surveys.
