egységmérséklet
Egységmérséklet, meaning "unit temperature" in Hungarian, is a conceptual term used primarily in older scientific or technical contexts to refer to a standard or baseline temperature against which other temperatures are compared. It is not a formally recognized unit of measurement in modern international systems like the SI. Instead, it represented a reference point, often the freezing point of water or a similar readily accessible temperature, used for calibration or to simplify calculations in specific applications.
The concept was more prevalent in an era before standardized temperature scales like Celsius and Fahrenheit
