Convert celsius to fahrenheit

Temperature conversion is a common task in various fields, from everyday life to scientific research. Different regions use different temperature scales, and converting temperatures between these scales is essential for clear communication and accurate calculations. Celsius (°C) and Fahrenheit (°F) are two commonly used temperature scales. Celsius is commonly used in most countries, while Fahrenheit is primarily used in the United States and a few other countries. Converting temperatures from Celsius to Fahrenheit is a fundamental conversion task.

Problem Statement and Description

The problem is to convert a temperature given in Celsius to its equivalent value in Fahrenheit. The Fahrenheit scale is based on a mixture of historical conventions and is often used for weather reporting in the United States. The conversion formula from Celsius to Fahrenheit is (celsius × 9/5) + 32, where you multiply the Celsius temperature by 9/5 and then add 32 to get the equivalent temperature in Fahrenheit.

Example

To better understand the problem, let's consider an example. Suppose we have a temperature of 20°C that we want to convert to Fahrenheit. Using the formula:

Fahrenheit = (Celsius × 9/5) + 32
Fahrenheit = (20 × 9/5) + 32
Fahrenheit = 68

So, 20°C is equivalent to 68°F.

Idea to Solve the Problem

To solve this problem, we need to develop a program that takes a temperature in Celsius as input, applies the conversion formula, and outputs the equivalent temperature in Fahrenheit. We will define a function to perform this conversion, and the main program will call this function for different test cases.

Pseudocode

Here's the pseudocode for the program:

function celsius_to_fahrenheit(celsius):
    fahrenheit = (celsius × 9/5) + 32
    return fahrenheit

main:
    celsius_to_fahrenheit(1)
    celsius_to_fahrenheit(10.80)
    celsius_to_fahrenheit(21.50)

Algorithm Explanation

  1. Define the celsius_to_fahrenheit function that takes a parameter celsius.
  2. Inside the function, calculate the equivalent temperature in Fahrenheit using the formula (celsius × 9/5) + 32.
  3. Return the calculated temperature in Fahrenheit.
  4. In the main program, call the celsius_to_fahrenheit function with different test cases: 1, 10.80, and 21.50.
  5. Print the results.

Program solution

//C Program 
//Convert celsius to fahrenheit
#include <stdio.h>

//Find the fahrenheit of given celsius
void celsius_to_fahrenheit(double celsius)
{
	// Formula : (celsius × 9/5) + 32 
	// Calculate given celsius to fahrenheit 
	double fahrenheit = (celsius * (9 / 5.0)) + 32;
	//Display result
	printf("Celsius : %lf  Fahrenheit : %lf\n", celsius, fahrenheit);
}
int main()
{
	//Simple test
	celsius_to_fahrenheit(1);
	celsius_to_fahrenheit(10.80);
	celsius_to_fahrenheit(21.50);
	return 0;
}

Output

Celsius : 1.000000  Fahrenheit : 33.800000
Celsius : 10.800000  Fahrenheit : 51.440000
Celsius : 21.500000  Fahrenheit : 70.700000

Time Complexity

The time complexity of this program is constant for each conversion, as it involves simple arithmetic operations (multiplication and addition). The number of operations remains the same regardless of the input Celsius temperature. Thus, the time complexity is O(1).
