It doesn't matter to the person buying the property, but it will matter to me if I ever survey across the state line; South Carolina uses the international foot, whereas North Carolina uses the US foot. The statics book recommends expressing final answers with three significant figures, unless the first is 1, in which case they should have four. Intermediate results, including unit conversions, should be more precise. Pierre
