Weighing scale

Weighing scales (usually just “scales” in UK and Australian English, “weighing machine” in south Asian English or “scale” in US English) is a measuring instrument for determining the weight or mass of an object. Weighing scales are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized medical scales and bathroom scales are used to measure the body weight of human beings.
