Conversion issue on Acids and Titratable acidity

Hi All
I am new here. I have one problem that I would greatly appreciate your help.I have data of citric acid (dominant acid) and two other acids (malic and glutamic)of a certain garden fruit measured by spectrophometric method and they are given in
mg/gfw which is "miligram per gram of fresh weight".
However for some analytical purposes I would also want the percentage titratable acidity given as "% citric acid anhydrous". However my data does not include that measurement. Is it possible to derive the percentage titratable acidity from the actual three acid levels given in mg/gfw so that I can have a useful figure that could fairly correspond with an actual measurement of titratable acidity?
thanks !
