text: Soya's specific gravity is between 0.915 and 0.925.  \nhttp://www.chemicalland21.com/arokorhi/industrialchem/organic/SOYABEAN%20OIL.htm\nFor peanut oil it is 0.90-0.92.  \nhttp://www.nutrin.com/aro%20p%20oil-spec.htm\nhttp://www.nutrin.com/rostd%20p%20oil-spec.htm\n(I included both links to show that the specific gravity does not differ between aromatic and roasted peanut oil)\n\nDifferent sources may give slightly different numbers, so if this is for a school project, you will be fine so long as you cite your source.  And if it's for practical purposes, it's best to measure it yourself since different production techniques or different bean stock may produce slight variations.\n\nHope that helps!
