0C

0C is a notation that can refer to several different concepts, most commonly zero degrees Celsius, the temperature on the Celsius scale. The Celsius scale is widely used for weather, science, and daily life. The symbol for the unit is °C, and 0°C marks the freezing point of water at standard atmospheric pressure. In the International System of Units, 0°C corresponds to 273.15 kelvin and is commonly used as a reference point in thermometry and climate studies.

In hexadecimal notation, 0C represents the decimal value 12. In many programming languages, hexadecimal literals are written as 0x0C, but 0C may appear in contexts that omit the 0x prefix. The byte with hexadecimal value 0C in ASCII and Unicode corresponds to the form feed control character, which historically moved print heads or paged text to the next page.

The interpretation of 0C depends on context. Without a degree symbol or unit specification, it may be read as a temperature with implied Celsius, as a hex value, or as part of a code or identifier. Precision and clarity are important when using the notation to avoid ambiguity, especially in scientific, computing, or technical communications.
