Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology". [15] It establishes a common understanding of units, crucial to human activity. [2]
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage , a sound tone, or a ...

NCSL International (NCSLI) (from the founding name "National Conference of Standards Laboratories") is a global, non-profit organization whose membership is open to any organization with an interest in metrology (the science of measurement) and its application in research, development, education, and commerce.
Common tools and techniques of measurement system analysis include: calibration studies, fixed effect ANOVA, components of variance, attribute gage study, gage R&R, [1] ANOVA gage R&R, and destructive testing analysis. The tool selected is usually determined by characteristics of the measurement system itself.
In metrology (the science of measurement), a standard (or etalon) is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity. [1] Standards are the fundamental reference for a system of weights and measures, against which all other measuring devices are compared.
The National Physical Laboratory is involved with new developments in metrology, such as researching metrology for, and standardising, nanotechnology. [66] It is mainly based at the Teddington site, but also has a site in Huddersfield for dimensional metrology [67] and an underwater acoustics facility at Wraysbury Reservoir near Heathrow ...
