Tensile strength of paper

Nov 19 2014Tensile strength of paper is expressed in N/m Force per unit length everywhere I am looking for a way to convert the tensile strength of paper to N/m^2 Force per unit area I assume this is because the paper strength might not be proportional to its cross sectional area It should calculated separately for each paper weight
