Select the appropriate temperature unit options and then enter your figure into any field of the Temperature Converter and get the converted value.
Temperature conversion formulas
The two most widely used units of temperature measurement are Fahrenheit and Celsius. The first was proposed in 1724 and is still used as the official scale in the USA. On this scale the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point is 212 °F. The other one is called the Celsius scale which is also defined by the freezing and boiling points of water. In the Celsius scale water freezes at close to 0 degrees Celsius (°C) and boils at close to 100 °C.
The Kelvin scale is an absolute temperature scale using as its initial point the absolute zero which is the temperature at which all thermal molecular motion ceases in the classical description of thermodynamics. The Kelvin is defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water (exactly 0.01 °C or 32.018 °F), so the triple point of water is exactly 273.16 K.
One Celsius degree is an interval of 1 K, and zero Celsius degree is 273.15 K. An interval of one Celsius degree corresponds to an interval of 1.8 Fahrenheit degrees on the Fahrenheit temperature scale.
The following formulas are used to convert from one temperature scale to another:
T(K) = T(°C) + 273.15,
T(°F) = T(°C) × 1.8 + 32,
T(K) = (T(°F) + 459.67)/1.8.
