Temperature
Temperature units converter. Easy conversion of Kelvin, Celsius, Fahrenheit, Rankine and other temperature related (heat) units.
What is "temperature"?
Defined according to wikipedia: Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Specifically, temperature is a property of matter.
Units
The Kelvin is the base unit of temperature in SI. Other common temperature units are: degree Celsius, degree Fahrenheit, degree Rankine, degree Delisle, degree Newton, degree Réaumur, degree Rømer.

Units in converter are (some additional info included):
  • Kelvin - the SI base unit. Defined by two points:
    • 0 K is absolute zero - the lowest possible temperature. No heat energy remains in a substance, so nothing could be colder. It is equal to -273.15°C and -459.67°F
    • 273.16 K is triple point of water (precisely: Vienna Standard Mean Ocean Water) - which is equal to 0.01°C and 32.018°F
  • degree Celsius (°C) - named after Anders Celsius (1701 – 1744).
    The 0°C on the Celsius scale was defined as the freezing point of water and 100°C was defined as the boiling point of water under a pressure of one standard atmosphere. This definition was valid from 1744 and is still really close to current definition.
    Currently "degree Celsius" is defined as:
    • −273.15 °C is absolute zero - the lowest possible temperature.
    • 0.01 °C is triple point of water - precisely: Vienna Standard Mean Ocean Water.
  • This was redefined in 1954 by international agreement - and makes the Celsius unit intervals equal to Kelvin intervals.
  • degree Fahrenheit (°F) - freezing point of water is 32 °F and the boiling point 212 °F.
  • degree Rankine (°R, °Ra) - 0 °R is absolute zero, however Rankine degree is defined as equal to one degree Fahrenheit. This means, that intervals for Fahrenheit and Rankine is the same, only "zero point" is different.
  • degree Delisle (°De)
  • degree Newton (°N)
  • degree Réaumur (°Ré)
  • degree Rømer (°Rø)

How to convert?
  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    Examples:
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit".
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you need.
