1tbls =15gms
5and1/3 tbls =1/3 cup
so it is roughly 1tbls=15gms

funny you asked cause i did a search on this one night trying to figure out the equivalents of dry weight. but it turned out to be about 15gms per tbls
or you can take a table spoon and empty it into a 1/3 measuring cup then divide the number of scoops by the carb total in the cup.
