Weight measurement refers to the process of determining how heavy an object is. It is typically expressed in units such as grams, kilograms, or pounds. Various tools, like scales and balances, are used to measure weight accurately. These instruments work by comparing the weight of an object to a known standard. The importance of weight measurement spans many fields, including science, health, and commerce. In healthcare, for example, monitoring a person's weight can help assess their overall health. In commerce, accurate weight measurement ensures fair trade and pricing of goods, such as food products and materials.
