Hello! I am currently working with openlca and ecoinvent 3.4 database. I have to apply a zinc coating to a tube of steel with lateral area of 2.07 m^2, 6 m of height and 78 kg. At the beginning I used directly 2.07 m^2 as amount using the process called "zinc coating coil" but my final impact results were too unbalanced. Then I read in the description of the coating process this phrase: "This module is applicable, if continuous zinc coating (galvanising) of hot or cold rolled strip- or wire-coils has to be inventoried. Data given per tonne of coated product are transformed by dividing them by the mean surface area of 64 m2/t."

To obtain the right m^2 is it correct to use make the following calculations: 78/1000/64? Thank you for your answer!
