273C
273C is a temperature measurement in the Celsius scale, which is part of the metric system. It is equivalent to 0 degrees Celsius, which is the freezing point of water under standard atmospheric conditions. This temperature is also known as the melting point of ice. In the Fahrenheit scale, 273C is equivalent to 32 degrees Fahrenheit. The term "273C" is often used in scientific and engineering contexts to denote the freezing point of water, which is a crucial reference point in many physical and chemical processes. It is also significant in the context of the Kelvin scale, where 273.15K is exactly equal to 0 degrees Celsius, making it a key conversion point between these two temperature scales.
