scales

Scales are tools used to measure weight or mass, often appearing as flat surfaces with a marked system for reading. They work by translating the force of gravity acting on an object into a numerical value. Different types include digital scales, which display weight electronically, and mechanical scales, which use springs and dials. Scales are used in various settings, such as weighing people, foods, or materials, to ensure accurate measurement for health, cooking, or scientific purposes. Proper calibration and understanding of their units (like pounds or kilograms) ensure they provide reliable readings.
