Kelvin Degrees Temperature Converter
Perform temperature conversions between different measurement systems.
A degree Celsius is a unit used in this type of scale. Its symbol is °C, and it is specifically used as a unit of temperature (the physical quantity that reveals the level of heat). This scale, also called the Celsius degree, has the freezing point of water as the value 0 and the boiling point of water as the value 100, always at normal pressure.
Fahrenheit is a thermodynamic temperature scale where the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point is 212 °F (at normal atmospheric pressure). This places the boiling and freezing points of water exactly 180 degrees apart. Therefore, one degree on the Fahrenheit scale is 1/180 of the interval between the freezing and boiling points of water. Absolute zero is defined as -459.67 °F.
Rankine is the temperature scale defined by measuring in degrees Fahrenheit above absolute zero, so it lacks negative values. The Rankine degree has its absolute zero point at −459.67°F, and the degree intervals are identical to the Fahrenheit degree interval.
The Réaumur scale, also known as the "octogesimal division," is a temperature scale where the freezing and boiling points of water are set at 0 and 80 degrees, respectively. The scale is named after René Antoine Ferchault de Réaumur, who proposed something similar in 1730.
