Weighing instruments are devices used to measure the weight or mass of an object. Common types include scales, balances, and load cells. These instruments can be found in various settings, from kitchens and laboratories to industrial environments, ensuring accurate measurements for different applications. Scales typically measure weight using a spring mechanism or electronic sensors, while balances compare the mass of an object against known weights. Digital scales provide easy-to-read measurements, while mechanical balances often require manual adjustments. Overall, weighing instruments play a crucial role in science, commerce, and everyday life by providing essential data for decision-making.
