Mittaustieteen

Mittaustiede, also known as metrology, is the science of measurement. It encompasses the theoretical and practical aspects of all measurements, regardless of the uncertainty in the measurement and the field of application. Metrology is divided into three main branches: scientific metrology, industrial metrology, and legal metrology.

Scientific metrology is concerned with the establishment of measurement units, the development of new measurement methods, and the research into measurement standards. It plays a crucial role in advancing scientific understanding and technological innovation by ensuring the accuracy and consistency of measurements across different disciplines.

Industrial metrology focuses on the practical application of measurement science in manufacturing and production processes. It involves the calibration of measuring instruments, the development of quality control systems, and the measurement of product dimensions and properties to ensure compliance with specifications and standards.

Legal metrology deals with the measurement regulations and standards that are mandated by law. Its primary objective is to ensure that measurements used in commercial transactions, legal proceedings, and public safety are accurate and reliable. This includes the verification and certification of measuring instruments used in trade, such as scales and fuel dispensers.

The fundamental principles of metrology are based on the International System of Units (SI), which provides a coherent and consistent framework for all measurements. Metrology ensures that measurements are comparable and reproducible worldwide, facilitating international trade, scientific collaboration, and technological development. It is a vital discipline that underpins many aspects of modern society.
