**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.

**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.**
