Calibration
Calibration refers to the process of setting the magnitude of the output (or response) of a measuring instrument to the magnitude of the input property or attribute within specified accuracy and precision. For example, a
thermometer could be calibrated so that it showed the temperature in
Celsius at the correct point.
For physical constants, weights, and measures, there are known and agreed values in the . Such constants include the length of the
metre, the mass of the
kilogram, and the volume of a
litre.
In the
United States, the
National Institute of Standards and Technology, a part of the federal government, maintains standards and is considered the arbiter and ultimate (in the U.S.) authority for values of SI units and industrial standards. NIST also defines
traceability, by which an instrument's accuracy is established in an unbroken chain relating an instrument's measurements through one or more derivative standards to a standard maintained by NIST, as well as
uncertainty.
In science, a calibrated test tube is one with measurements up the side. In computing, an
interactive whiteboard pen or other input method can be calibrated so that it moves the
cursor to the correct point on the screen.
