The INEVIFIT Kitchen Scale is sensitive to 1-gram increments. All weights are measured in grams and then displayed as the converted equivalent in pounds, ounces, or ml. In the case of ounces, 1-gram = 0.0353 oz. Therefore the scale will either display; 28 grams = 0.988 oz OR 29 grams = 1.023 oz *Either way it will be within one gram of at any measurement.
