Measurement instruments are tools used to determine the size, amount, or degree of something. They help us quantify various properties, such as length, weight, temperature, and time. Common examples include a ruler for measuring distance, a scale for weighing objects, and a thermometer for checking temperature. These instruments are essential in fields like science, engineering, and everyday life. Different measurement instruments are designed for specific tasks, ensuring accuracy and reliability. For instance, a caliper can measure small distances with precision, while a stopwatch is perfect for timing events. Understanding how to use these tools effectively is crucial for obtaining correct measurements and making informed decisions.
