Converting temperatures from Celsius (°C) to Fahrenheit (°F) is essential for understanding different measurement systems. This tutorial explains how to convert 43°C to °F step by step using a formula. We’ll also provide programs in C, C++, Java, and Python to automate the calculation.

Conversion Formulas : °C to °F

To better understand the relationship between Celsius and Fahrenheit, here are the conversion formulas:

Celsius to Fahrenheit

F=Cimes95+32F = C imes \frac{9}{5} + 32

Where:

  • F = Temperature in Fahrenheit
  • C = Temperature in Celsius

Fahrenheit to Celsius

C=(F−32)imes59C = (F – 32) imes \frac{5}{9}

These formulas help convert between the two temperature scales efficiently.

Step-by-Step Conversion of 43°C to Fahrenheit

Step 1: Write the formula

F=Cimes95+32F = C imes \frac{9}{5} + 32

Step 2: Substitute the value of C (43°C)

F=43imes95+32F = 43 imes \frac{9}{5} + 32

Step 3: Perform the multiplication

43imes95=43imes1.8=77.443 imes \frac{9}{5} = 43 imes 1.8 = 77.4

Step 4: Add 32 to the result

77.4+32=109.477.4 + 32 = 109.4

Thus, 43°C = 109.4°F.

Programs to Convert Celsius to Fahrenheit

C Program

#include <stdio.h>

int main() {
    float celsius = 43.0;
    float fahrenheit;

    fahrenheit = celsius * (9.0 / 5.0) + 32;

    printf("%.2f°C is equal to %.2f°F\n", celsius, fahrenheit);

    return 0;
}

C++ Program

#include <iostream>
using namespace std;

int main() {
    float celsius = 43.0;
    float fahrenheit;

    fahrenheit = celsius * (9.0 / 5.0) + 32;

    cout << celsius << "°C is equal to " << fahrenheit << "°F" << endl;

    return 0;
}

Java Program

public class CelsiusToFahrenheit {
    public static void main(String[] args) {
        double celsius = 43.0;
        double fahrenheit;

        fahrenheit = celsius * (9.0 / 5.0) + 32;

        System.out.printf("%.2f°C is equal to %.2f°F\n", celsius, fahrenheit);
    }
}

Python Program

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

celsius = 43.0
fahrenheit = celsius_to_fahrenheit(celsius)

print(f"{celsius:.2f}°C is equal to {fahrenheit:.2f}°F")

Practical Applications

  1. Weather Understanding: Many countries use Celsius, while the U.S. uses Fahrenheit. Converting helps interpret temperature readings.
  2. Science Experiments: Temperature conversions are crucial in experiments requiring precise measurements.
  3. Cooking: Recipes often interchange between Celsius and Fahrenheit.

Summary

By following the step-by-step method, we calculated that 43°C = 109.4°F. With the provided programs in C, C++, Java, and Python, you can easily automate this conversion and apply it in various scenarios. Explore these examples to enhance your understanding of temperature conversions and programming!
