Metrology is the science of measurement

SI Units - second, metre, kilogram, ampere, kelvin, mole, candela

What is a CMM?

A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light
