Temperature Conversion Calculator and Formula (C to F to K to C)

Temperature Conversion is a process of changing temperature value from one unit to another (C to F to K to C). Mostly there are 3 units in the world, used to measure the temperature and these three units are- Celsius, Fahrenheit and Kelvin. And if we want to change values of one unit to another temperature conversions are required. These Temperature conversions are based on some formulas also called as Temperature Conversion Formula. Every country on this earth except United States uses Celsius scale/ units to measure temperature. Fahrenheit is officially used in countries like- United States and its dependencies. Kelvin is not used by any country to measure everyday temperature, It is used by the Scientists worldwide.

Possible Temperature Conversions Based on 3 Units

Mainly three units (Celsius, Fahrenheit and Kelvin) and used to measure the temperature and the possible conversions are 6- listed below-. And people generally search for these 6 possible pairs for conversion of temperature.

1. Celsius to Fahrenheit Conversion (°C to °F)
2. Fahrenheit to Celsius Conversion (°F to °C)
3. Fahrenheit to Kelvin Conversion (°F to K)
4. Kelvin to Fahrenheit Conversion (K to °F)
5. Celsius to Kelvin Conversion (°C to K)
6. Kelvin to Celsius Conversion (K to °C)

Celsius- The Celsius temperature still up in the air by peaceful accord concerning two fixed focuses; the ice point and the stream point. The temperature of the ice point is characterized as 0° Celsius and the stream point as 100° Celsius.

Kelvin- The meaning of the Kelvin is the portion 1/273.16 of the thermodynamic temperature of the triple place of water. The unit of Kelvin or thermodynamic temperature scale is known as the Kelvin.

Fahrenheit is a temperature scale based on freezing (32°F) and boiling point of water (212°F), And this scale is mostly used in United States. Average body temperature in this scale is- 98.6°F.

1. Celsius to Fahrenheit Formula (°C to °F)

Conversion of temperature from Celsius to Fahrenheit is performed by the following formula and steps-

°F = °C × (9/5) + 32

Example– How to Convert -78 Celsius to Fahrenheit ?

• °F = (-78 °C) × 9/5 + 32;  = -108.4°F Answer.  (For more conversions use our tool in top of this page).

2. Fahrenheit to Celsius Formula (°F to °C)

Conversion of temperature from Fahrenheit to Celsius is performed by the following formula and steps-

°C = [(°F-32)×5]/9

Example– How to Convert -117 Fahrenheit to Celsius ?

• °C = [(-117 F – 32) × 5] / 9;  =  -82.7778 °C Answer.

3. Fahrenheit to Kelvin Formula (°F to K)

Conversion of temperature from Fahrenheit to Kelvin is performed by the following formula and steps-

K = (F − 32) × 5/9 + 273.15

Example– How to Convert 32 Fahrenheit to kelvin ?

• K = (32 − 32) × 5/9 + 273.15;  =  273.15 K Answer.

4. Kelvin to Fahrenheit Formula (K to °F)

Conversion of temperature from Kelvin to Fahrenheit is performed by the following formula and steps-

°F = [K − 273.15] × 9/5 + 32

Example– How to Convert 300 Kelvin to Fahrenheit ?

°F = (300 − 273.15) × 9/5 + 32;  =  80.33°F Answer.

5. Celsius to Kelvin Formula (°C to K)

Conversion of temperature from Celsius to Kelvin is performed by the following formula and steps-

K = °C + 273.15;

Example– How to Convert -78 c to k ?

K = (-78) + 273.15;  =  195.15 K  Answer.

6. Kelvin to Celsius Formula (K to °C)

Conversion of temperature from Kelvin to Celsius is performed by the following formula and steps-

°C = K – 273.15

Example– How to Convert 273 Kelvin to Celsius ?

°C = 273 – 273.15;  =  -0.15 °C  Answer.
