Digital tape measure is like a digital-to-analog converter, where the digital data is converted to analog data.
But digital tape measures are more precise than analog ones, which can only be used for measurements of linear or curved surfaces.
A digital tape measurement is an accurate way to measure a surface at any scale, including linear and curved surfaces, with an accuracy of about 0.01 millimeters per inch (0.0025 millimeters).
Digital tape measures typically have an accuracy rate of about 100 millimeters.
They can also be used to measure linear surfaces with a measurement range from 0 to about 20 microns, which is about the thickness of a human hair.
