PHP code: convert Celsius into Fahrenheit using function

PHP code: convert Celsius into Fahrenheit using the function

In this tutorial, we will discuss the concept of the PHP code: convert Celsius into Fahrenheit using the function

In this post, we will learn how to write a program to convert Celsius into Fahrenheit using the function in PHP programming language with an Example program.

Temperature and conversion

Generally, We have known three types of temperature units Fahrenheit, Celsius, and Kelvin. In this article, we are discussing how to convert temperature units Celsius into Fahrenheit. Fahrenheit and Celsius are the measuring units in degrees as ⁰F and ⁰C  respectively.

scientific equation Fahrenheit= Celsius*9/5+32

Program to Celsius into Fahrenheit

Convert Celsius into Fahrenheit using the function – via variable

In this program, the user declares a double variable as a parameter for Celsius in the user-defined function. When the user calls the function, the Celsius value passes to the function as an argument through the variable.
Finally, the Fahrenheit value is calculated and displayed on the screen using the function in the PHP programming language.

Program 1

<?php
function calc_Fahrenheit(int $celsius){
return ($celsius *9/5)+32;
}
$celsius=100;

echo("The temperature in Fahrenheit is: ");
//$celsius=round($celsius,3);
echo(calc_Fahrenheit($celsius));

When the above code is executed, it produces the following result

The temperature in Fahrenheit is: 212

Convert Celsius into Fahrenheit using the function

Program 2

In this program, the user declares a double variable as a parameter for Celsius in the user-defined function. When the user calls the function, the Celsius value passes to the function as an argument.
Finally, the Fahrenheit value is calculated and displayed on the screen using the function in the PHP programming language.

<?php
function calc_Fahrenheit(int $celsius){
return ($celsius *9/5)+32;
}

echo("Temperature in Fahrenheit is: ");
//$celsius=round($celsius,3);
echo(calc_Fahrenheit(100));
echo "\n";
echo(calc_Fahrenheit(0));
echo "\n";
echo(calc_Fahrenheit(50));

When the above code is executed, it produces the following result

The temperature in Fahrenheit is: 212
32
122

Convert Celsius into Fahrenheit using the function-Entered by the user

Program 3

In this program, the user declares a double variable as a parameter for Celsius in the user-defined function. When the user runs the program (calling the function), the program is asked for the value for Celsius and stores the given value in the variable Celsius for an argument in the function.
Finally, the Fahrenheit value is calculated using scientific equations and displayed on the screen

<?php
function calc_Fahrenheit(int $celsius){
return ($celsius *9/5)+32;
}
$celsius=readline("Enter the Celsius: ");

echo("The temperature in Fahrenheit is: ");
//$celsius=round($celsius,3);
echo(calc_Fahrenheit($celsius));

When the above code is executed, it produces the following result

Enter the Celsius: 90
The temperature in Fahrenheit is: 194
