We normally use body weight as the sole measure for determining whether someone is over or underweight, but this is not accurate. Because fat takes up three times the space of muscle,people with too much fat will look more obviously overweight. Therefore, body fat percentage is the measure for determining whether someone is over or underweight. A precise, comprehensive body fat scale can also help you to understand your body better. The G-shaped manganese steel sensor is able to sense weight changes as small as 50 g, which makes the Mi Body Composition Scale 2’s measurements more precise. Weighing also supports switching between jin, kilograms and pounds for easy reading.
