Weighing scales are devices used to measure the weight of objects. They come in various types, such as digital scales and mechanical scales, each serving the same purpose but using different methods. Digital scales provide a numerical readout, making it easy to see the weight, while mechanical scales use a dial and a pointer. These scales are commonly found in homes, kitchens, and grocery stores. In the kitchen, they help with cooking by ensuring the right amount of ingredients. In grocery stores, they assist customers in weighing fruits, vegetables, and other products before purchasing them.
