One "scoop" is approximately 1/8 ounce, by weight, of coffee. I have several different coffee scoops and, althought they are different shapes and materials, they hold pretty much the same amount of coffee, and the weight was the same whether I scooped whole beans or ground coffee. I normally use one scoop for every two cups the coffeemaker says it makes, which should give you a ball park figure, but you are going to have to experiment for your own taste because I don't know how strong you like your coffee.
