Professional coffee tasters use: exactly two (2) tablespoons (7 to 9 grams or 2 scoop of a standard coffee measure) of ground coffee beans for each six (6) ounces of water. For 4 cups (6 ounces each) of coffee, measure out 8 generous tablespoons (30 to 35 grams) of fresh ground coffee beans.
By the way, if you are talking about beans, a tablespoon of beans  is the same volume as a tablespoon of even very fine ground (once  the same beans are ground), but weighs more-- 1/2 cup or 5  tablespoons of beans is 114 grams (4 ounces), almost twice the  WEIGHT as the finely ground same coffee.
