The measurements on a digital food scale are easy to read. Digital weighing scales for food measure the weight of food in pounds (lbs), ounces (oz), kilograms (kg), and grams (g). After placing the sample on the scale, a number will appear on the digital display. There will be a unit of measurement next to that number, which is the weight of that specific food sample. For example, if it weighs two kilos, it would be shown as 2kg.
