Weighing is the process of determining the mass of an object using a scale or balance. It involves comparing the object to a known standard, often measured in units like grams or pounds. This measurement helps in various fields, including cooking, science, and shipping, where knowing the weight is essential for accuracy. There are different types of scales, such as digital and mechanical, each functioning based on principles of physics. For example, a spring scale measures weight by the distance a spring stretches under the load. Accurate weighing is crucial for tasks ranging from laboratory experiments to grocery shopping.
