A clove of garlic may weight up to 5 grams, but of course this all depends on the size. Remember, a clove is just one small piece that you break off. Like a leaf. The whole bulb, rounded and unbroken will also vary in weight due to its size. Do you have a scale. This is best way to determine. All in all, if eating for health reasons, go ahead and have fun with garlic. It is a natural antibiotic as well, keeps blood sugar down in body, to help prevent diabetes and gives wonderful flavor to food, whether raw, like in salads or cooked. Enjoy, one of my favourites
