Is this coffee ratio calculation correct?
Yes. Strangely, a standard "cup" of coffee (at least in the US) is 6 ounces (177ml). That's especially weird since most of us drink huge mugs. Go figure. So according to Folgers, to make 8 "servings" (48 ounces, 1.4 liters) you should use 8 tablespoons of coffee (42 grams) and 6 cups (48 ounces, 1.4 liters) of water.
