meraná

Meraní is the act or process of determining the size, amount, or position of something by comparing it with a standard or reference. It is a core concept in metrology and is used across science, engineering, industry, and daily life.

The term is used in several Slavic languages and is related to measurement. In practice, meraní encompasses planning, data collection, analysis, and reporting of quantities such as length, mass, time, temperature, electrical signals, and geographic coordinates.

Typical procedure: define the quantity and unit, select appropriate instrument, perform measurement, estimate measurement uncertainty, document results, and repeat when necessary. Measurements rely on reference standards and calibration against known values. Instruments require calibration, maintenance, and documentation.

Standards and traceability: Measurements rely on reference standards and calibration against known values. Instruments require calibration, maintenance, and documentation.

History and scope: From simple rulers and sundials to digital sensors and atomic clocks, meraní has evolved with technology. Modern metrology emphasizes accuracy, precision, repeatability, and comparability across laboratories and industries. Quality and reliability depend on controlling systematic and random errors and ensuring traceability.
