5 tablespoons plus 1 teaspoon of butter equals one-third of a cup so two-thirds of a cup would be 10 tablespoons plus 2 teaspoons... hope that helps in figuring out the gram equivalent

There are sixteen tablespoons in a fluid ounce. There are eight fluid ounces in one cup. So there are 128 tablespoons in one cup. For a half cup, it will be 64 tablespoons. So 128 tablespoons + 64 tablespoons = 192 tablespoons. Hope this satisfies your question!
