Food scales range in price from under $10 to over $30, as of 2015. Nutritional scales measure foods for dieters, while cooking scales weigh dry ingredients, such as flour, for more precision. Both digital and analog scales are available, as are high-capacity food scales weighing up to 22 pounds.
Analog mechanical scales allow the user to weigh food without requiring a battery. The user sets the zero on the scale, adds the food and reads the weight off a dial. The digital readout on electronic scales is easier to read and eliminates any guesswork. Some scales have a backlight, making it easier for the user to read the weight.
