WAP that accepts the temperature in Centigrade and converts into Fahrenheit using the formula C/5=(F-32)/9. content

Concept

The concept of converting temperature from Celsius to Fahrenheit using the formula C/5 = (F-32)/9 involves understanding the relationship between the two temperature scales and applying the conversion formula. Let’s break down the concept step by step:

1. Understanding Celsius and Fahrenheit:
   • Celsius (°C) and Fahrenheit (°F) are two commonly used temperature scales.
   • The Celsius scale is based on the freezing and boiling points of water, where 0°C represents the freezing point and 100°C represents the boiling point at sea level.
   • The Fahrenheit scale is primarily used in the United States and some other countries. It also has the freezing and boiling points of water, but they are set at 32°F and 212°F, respectively.
2. Conversion Formula:
   • The conversion formula between Celsius and Fahrenheit is derived from the relationship between the two scales.
   • The formula is: C/5 = (F-32)/9
   • Here, C represents the temperature in Celsius, and F represents the temperature in Fahrenheit.
3. Applying the Conversion Formula:
   • To convert Celsius to Fahrenheit, we need to rearrange the formula to solve for F.
   • By cross-multiplying and simplifying the equation, we get: F = (C * 9/5) + 32
   • This equation can be used to convert any temperature in Celsius to Fahrenheit.
4. Using the Conversion Formula in a Program:
   • To apply the conversion formula in a program, we need to accept the temperature in Celsius as input and perform the calculation.
   • We can create a function that takes the Celsius temperature as an argument, applies the formula, and returns the equivalent temperature in Fahrenheit.
   • The formula F = (C * 9/5) + 32 is used inside the function to perform the conversion.
5. Displaying the Result:
   • Once the conversion is performed, the result (temperature in Fahrenheit) can be displayed to the user.
   • The program can use a print statement to output the converted temperature.

By understanding the relationship between Celsius and Fahrenheit and applying the conversion formula, we can convert temperatures accurately between the two scales. This concept can be implemented in programming languages to create a Celsius-to-Fahrenheit conversion program that accepts input, performs the calculation, and displays the result.

Example in C Programming

Here’s a C program that accepts a temperature in Celsius and converts it to Fahrenheit using the given formula:

#include <stdio.h>

float celsius_to_fahrenheit(float celsius) {
    float fahrenheit = (celsius * 9/5) + 32;
    return fahrenheit;
}

int main() {
    float celsius, fahrenheit;

    printf("Enter the temperature in Celsius: ");
    scanf("%f", &celsius);

    fahrenheit = celsius_to_fahrenheit(celsius);

    printf("The temperature in Fahrenheit is: %.2f\n", fahrenheit);

    return 0;
}

In this program, we define a function celsius_to_fahrenheit that takes the temperature in Celsius as a parameter, applies the formula (C/5) = (F-32)/9 to convert it to Fahrenheit, and returns the result.

In the main function, we declare variables celsius and fahrenheit to store the user input and the converted temperature, respectively.

The printf function is used to prompt the user to enter the temperature in Celsius, and the scanf function is used to read the input value and store it in the celsius variable.

Next, we call the celsius_to_fahrenheit function, passing the celsius value as an argument, and assign the returned result to the fahrenheit variable.

Finally, we use the printf function to display the converted temperature in Fahrenheit with two decimal places.

You can compile and run this C program, provide a temperature in Celsius, and it will output the equivalent temperature in Fahrenheit.

Example in C++

In this C++ program, we define a function celsius_to_fahrenheit that takes the temperature in Celsius as a parameter, applies the formula (C/5) = (F-32)/9 to convert it to Fahrenheit, and returns the result.

In the main function, we declare variables celsius and fahrenheit to store the user input and the converted temperature, respectively.

We use the std::cout statement to prompt the user to enter the temperature in Celsius, and the std::cin statement to read the input value and store it in the celsius variable.

Next, we call the celsius_to_fahrenheit function, passing the celsius value as an argument, and assign the returned result to the fahrenheit variable.

Finally, we use the std::cout statement to display the converted temperature in Fahrenheit.

#include <iostream>

float celsius_to_fahrenheit(float celsius) {
    float fahrenheit = (celsius * 9 / 5) + 32;
    return fahrenheit;
}

int main() {
    float celsius, fahrenheit;

    std::cout << "Enter the temperature in Celsius: ";
    std::cin >> celsius;

    fahrenheit = celsius_to_fahrenheit(celsius);

    std::cout << "The temperature in Fahrenheit is: " << fahrenheit << std::endl;

    return 0;
}

Output of C++

Example of Java

In this Java program, we define a method celsiusToFahrenheit that takes the temperature in Celsius as a parameter, applies the formula (C/5) = (F-32)/9 to convert it to Fahrenheit, and returns the result.

In the main method, we create a Scanner object to read the user input.

We use the System.out.print statement to prompt the user to enter the temperature in Celsius, and the scanner.nextFloat method to read the input value and store it in the celsius variable.

Next, we call the celsiusToFahrenheit method, passing the celsius value as an argument, and assign the returned result to the fahrenheit variable.

Finally, we use the System.out.println statement to display the converted temperature in Fahrenheit.

import java.util.Scanner;

public class CelsiusToFahrenheit {
    public static float celsiusToFahrenheit(float celsius) {
        float fahrenheit = (celsius * 9 / 5) + 32;
        return fahrenheit;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter the temperature in Celsius: ");
        float celsius = scanner.nextFloat();

        float fahrenheit = celsiusToFahrenheit(celsius);

        System.out.println("The temperature in Fahrenheit is: " + fahrenheit);

        scanner.close();
    }
}

Output

Example in python

def celsius_to_fahrenheit(celsius):
    fahrenheit = (celsius * 9/5) + 32
    return fahrenheit

# Accept temperature in Celsius from the user
celsius = float(input("Enter the temperature in Celsius: "))

# Convert Celsius to Fahrenheit
fahrenheit = celsius_to_fahrenheit(celsius)

# Print the result
print("The temperature in Fahrenheit is:", fahrenheit)
