measuring instruments

Measuring instruments are tools used to determine specific quantities or parameters, such as length, weight, temperature, or pressure. Common examples include rulers for measuring distance, scales for weight, thermometers for temperature, and barometers for atmospheric pressure. These instruments are essential in various fields, including science, engineering, and everyday life, as they provide accurate data to inform decisions and understand the world. Each instrument works on specific principles—like the expansion of liquids in thermometers or the displacement of water for volume measurements—ensuring reliability and precision in measurements.
