Cryometry is a term that refers to the measurement of very low temperatures, typically those below −150 °C. Synonyms for the term include cryology and low-temperature physics, which both represent the study and measurement of extremely cold temperature. Moreover, cryogenics, cryophysics, and refrigeration engineering are also similar terms to cryometry that focus on low-temperature processes and technology. Additionally, cryonics, which refers to the preservation of humans and animals in a suspended state for potential revival in the future, can also be related to cryometry. Overall, these synonyms for cryometry highlight the importance and applications of low-temperature research in various fields of science and technology.
