What is linear measurement in metrology?

Linear measurement includes the measurement of lengths, diameters, heights and thickness. The basic principle of linear measurement (mechanical type) is that of comparison with standard dimensions on a suitably engraved instrument or device. Linear measuring instruments are categorized depending upon their accuracy.

What is linear measurement?

Linear measurement is when you measure things in a straight line using tools such as a ruler, yardstick or tape measure. Note: Metric and/or imperial units can be used to measure linear measurements. One example is provided for each type of linear measurement.
