Mérése

Mérése is a term in Hungarian that refers to measurement, the act of determining a quantity relative to a standard. As a broad practice, it spans natural sciences, engineering, commerce, and everyday life, providing a means to compare, quantify, and communicate information about physical properties such as length, mass, time, temperature, and chemical concentration. The study of measurement falls under metrology, the science of measurement, including the definition of units, the assessment of measurement accuracy, and the establishment of traceability to standards.

Key concepts include accuracy, precision, resolution, and uncertainty. Accuracy indicates how close a measurement is to the true value; precision reflects the reproducibility of repeated measurements; resolution is the smallest detectable change given the instrument. Uncertainty expresses the doubt associated with a result and is often quantified in an uncertainty budget.

Measurement units are defined in the International System of Units (SI). Most practical measurements derive from SI through calibration, a process that links an instrument to standards via a chain of comparisons. Traceability ensures that results are comparable across times and places.

Applications of Mérése are widespread, from quality control in manufacturing and laboratory experiments to environmental monitoring, healthcare, and consumer technology. Instruments range from simple rulers and scales to advanced spectrometers and atomic clocks, all supported by national and international metrology organizations that maintain standards, promote best practices, and coordinate international comparisons.
