Temperature Conversion Formulas
Before going to know the Temperature conversion formulas let us understand what is temperature and its units? And how it is measured? And How do we convert temperature into different units?
Definition of Temperature:
Temperature is the is a measure of matter which reflects the quantity of energy of motion ( kinetic energy ) of the component particles. The higher the temperature of a material, the higher is its kinetic energy. Similarly, the lower the temperature of a material, the lower is its kinetic energy. The temperature defines how cold or hot a material is. In short, the temperature is an expression of heat energy and represented by the letter (T).
The lowest temperature or where there is no heat in a system or substance, is called Absolute zero. Absolute zero is −273.15 C on the Celsius scale, 0 K on the Kelvin scale, and −459.67 F on the Fahrenheit scale.
From this, you may understand that there are three scales used to measure the temperature Celsius, Kelvin, and Fahrenheit. These three are the most commonly used scales.
- According to the Celsius scale, the boiling point water is 100°C, and the freezing point of water is 0°C.
- According to the Kelvin scale, the boiling point water is 373.15K, and the freezing point of water is 273.15K.
- According to the Fahrenheit scale, the boiling point water is 212°Fand the freezing point of water is 32°F.
Now let us see the formulas for Temperature Conversion
There are three primary conversions of temperature, which are:
- Conversion Between Celsius and Fahrenheit
- Conversion Between Celsius and Kelvin
- Conversion Between Fahrenheit and Kelvin

Temperature Conversion Between Fahrenheit and Celsius
- The formula for the temperature conversion from Fahrenheit to Celsius is: C = (F − 32) × 5⁄9
- The formula for the temperature conversion from Celsius to Fahrenheit is: F = C(9⁄5) + 32
Temperature Conversion Between Celsius and Kelvin
- The formula for the temperature conversion from Celsius to Kelvin is: K = C + 273.15
- The formula for the temperature conversion from Kelvin to Celcius is: C = K − 273.15
Temperature Conversion Between Fahrenheit and Kelvin
- The formula for the temperature conversion from Fahrenheit to Kelvin is: K = (F − 32) × 5⁄9 + 273.15
- The formula for the temperature conversion from Kelvin to Fahrenheit is: F = (K – 273.15) × 9⁄5 + 32
| Unit | To Celsius | To Fahrenheit | To Kelvin |
| Celsius (C) | C (°) | C(9⁄5) + 32 | C + 273.15 |
| Fahrenheit | (F − 32) × 5⁄9 | F | (F − 32) × 5⁄9 + 273.15 |
| Kelvin | K – 273.15 | (K – 273.15) * 9/5 + 32 | K |
Temperature scales are absolute or relative. The absolute scale is a measurement that begins at a minimum or zero points whereas in relative scale at their zero points arbitrarily have assigned. Both Fahrenheit and Celsius scales are relative temperature scales. The Kelvin scale is an example of an absolute scale that has no degrees.

5 Interesting facts about temperature
- The average temperature of the Sun surface is 5,600 Kelvin.
- Temperatures in the Universe range from about 3,500,000,000 Kelvin (a supernova) to 3 Kelvin (space).
- The process of transferring heat from a substance at a higher temperature to one at a lower temperature results Conduction (occurs in solid), convection (occurs in liquid) and radiation (takes place through space)
- Fahrenheit and Celsius are equal at -40 degrees.
- Temperature also defined as the speed at which molecules move higher the speed .higher is the temperature vice versa.
