This is a temperature calculator that supports conversions between various temperature scales like Celsius (C), Fahrenheit (F), Kelvin (K), Rankine, and Réaumur. It can be a useful tool for different applications.
Temperature Scales
- Celsius (C): Commonly used in most parts of the world. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
- Fahrenheit (F): Commonly used in the United States. Water freezes at 32°F and boils at 212°F at standard atmospheric pressure.
- Kelvin (K): The SI unit of temperature. Absolute zero, the lowest possible temperature, is 0 Kelvin.
- Rankine: An absolute temperature scale commonly used in thermodynamics. It is based on Fahrenheit degrees and starts at absolute zero.
- Réaumur: Historically used in some European countries. Water freezes at 0°Ré and boils at 80°Ré.
How to convert temperature?
The calculator allows you to convert temperatures easily between these scales. Common conversions include Celsius to Fahrenheit, Celsius to Kelvin, Fahrenheit to Celsius, and so on.
The conversion formulas are mathematical relationships between the different temperature scales, i.e.:
- How to convert Celsius to Fahrenheit ?
F = (9/5)C + 32 - How to convert Celsius to Kelvin ?
K = C + 273.15 - How to convert Fahrenheit to Celsius ?
C = (5/9)(F - 32) - How to convert Kelvin to Celsius ?
C = K - 273.15
