What is linear measurement?

Linear measurement is the process of determining the length or size of an object along a straight line. It is used in many applications, such as construction, manufacturing, and engineering, to ensure the correct size and dimensions of objects. Linear measurement can be done using a variety of tools, including rulers, tapes, and micrometers, and the units of measurement can range from millimeters to kilometers. The accuracy of linear measurement is important for ensuring that objects fit together properly, function as intended, and meet specific design requirements.
