Temperature conversion is the process of expressing temperatures in different units of measurement. The most commonly used temperature scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K). Converting temperatures between these scales is crucial in various fields such as science, meteorology, cooking, and everyday life. This guide provides a detailed overview of temperature conversion and the formulas used for accurate conversions.


Temperature Scales:


1. Celsius (°C):

The Celsius scale is commonly used in most of the world. The freezing point of water is 0°C, and the boiling point is 100°C at standard atmospheric pressure.


2. Fahrenheit (°F):

The Fahrenheit scale is used primarily in the United States and a few other countries. The freezing point of water is 32°F, and the boiling point is 212°F at standard atmospheric pressure.


3. Kelvin (K):

The Kelvin scale is an absolute temperature scale commonly used in scientific contexts. Zero Kelvin (0 K) is absolute zero, the lowest possible temperature where molecular motion ceases.


Conversion Formulas:


Celsius to Fahrenheit:

\[ °F = (°C \times \frac{9}{5}) + 32 \]


Fahrenheit to Celsius:

\[ °C = \frac{5}{9} \times (°F - 32) \]


Celsius to Kelvin:

\[ K = °C + 273.15 \]


Kelvin to Celsius:

\[ °C = K - 273.15 \]


Fahrenheit to Kelvin:

\[ K = \frac{5}{9} \times (°F - 32) + 273.15 \]


Kelvin to Fahrenheit:

\[ °F = (K \times \frac{9}{5}) - 459.67 \]


Example Conversions:


1. Convert 25°C to Fahrenheit:

   \[ °F = (25 \times \frac{9}{5}) + 32 \]

   \[ °F = 77°F \]


2. Convert 98.6°F to Celsius:

   \[ °C = \frac{5}{9} \times (98.6 - 32) \]

   \[ °C = 37°C \]


3. Convert 300 K to Celsius:

   \[ °C = 300 - 273.15 \]

   \[ °C = 26.85°C \]


Practical Applications:


1. Cooking:

Recipes may provide temperatures in Celsius or Fahrenheit, and converting between them is essential for accurate cooking.


2. Medical Fields:

Body temperatures are often measured in Celsius, but Fahrenheit is still used in some contexts.


3. Global Communications:

International collaboration and communication often require converting temperatures between Celsius and Fahrenheit.


4. Scientific Research:

Kelvin is commonly used in scientific research, especially in physics and chemistry, where absolute temperatures are crucial.


Online Temperature Converters:

Various online tools and mobile apps provide easy-to-use temperature converters for quick and accurate conversions.



Understanding temperature conversion is essential for accurate communication and practical applications in diverse fields. The ability to convert temperatures between Celsius, Fahrenheit, and Kelvin is a valuable skill for anyone working with temperature measurements.

Frequently Asked Questions FAQ

How to convert temperature C to F in C?
In C programming, you can convert temperature from Celsius to Fahrenheit using a simple formula. Here's a basic example in C: ```c #include int main() { // Declare variables for Celsius and Fahrenheit float celsius, fahrenheit; // Get temperature in Celsius from user input printf("Enter temperature in Celsius: "); scanf("%f", &celsius); // Convert Celsius to Fahrenheit using the formula: (C Γ— 9/5) + 32 fahrenheit = (celsius * 9/5) + 32; // Display the converted temperature in Fahrenheit printf("%.2f Celsius is equal to %.2f Fahrenheit\n", celsius, fahrenheit); return 0; } ``` In this program: 1. We declare two variables, `celsius` and `fahrenheit`, to store the temperature in Celsius and its equivalent in Fahrenheit. 2. We use `printf` and `scanf` to get the temperature in Celsius from the user. 3. The conversion formula `(C Γ— 9/5) + 32` is used to convert Celsius to Fahrenheit. 4. Finally, we use `printf` to display the original temperature in Celsius and its equivalent in Fahrenheit. Compile and run this C program, and it will prompt you to enter a temperature in Celsius, then it will calculate and display the equivalent temperature in Fahrenheit.
