Celsius Scales - definition
The Scales of Celsius is a commonly used way of expressing temperature in the metric system, based on the thermal properties of water. It was introduced in the 18th century by the Swedish astronomer Anders Celsius and was originally based on two reference points: the melting point of ice and the boiling point of water, measured at standard atmospheric pressure. In its modern definition, the scale is directly linked to the SI system and absolute temperature expressed in kelvins (K).
The unit of the Celsius Scales is the degree Celsius, denoted by the symbol '°C'. Currently, the value of one degree Celsius is identical to the value of one kelvin, while the shift of the zero reference point makes 0°C equivalent to 273.15 K. In this way, the Celsius Scales maintains consistency with thermodynamic physics and can be used in parallel with kelvins in the analysis of thermal processes. The scale is categorised as a so-called relative scale because its zero does not represent the absence of heat energy, but the freezing point of water.
The Celsius Scale is used in science, industry, meteorology, medicine and everyday life, being the standard in most countries of the world, with the exception of, among others, the United States, where the Fahrenheit Scale is widely used. Because of its intuitive reference to natural phenomena and its simple interpretation of temperature differences, this scale is particularly useful in describing environmental conditions and the performance of technical equipment.
