ITS-90 (International Temperature Scale of 1990)

The ITS-90 (International Temperature Scale of 1990) is a standard for measuring temperature accurately across a wide range, used globally in science and industry. It provides precise reference points, like the melting point of ice or boiling point of water, and uses advanced methods to interpolate temperatures between these points. This ensures consistency and comparability of temperature measurements worldwide, essential for scientific research, manufacturing, and technology. Essentially, ITS-90 acts as a universal language for temperature, helping teams and countries get reliable, uniform readings for critical applications.
