PHP code to convert Fahrenheit into Celsius

PHP code to convert Fahrenheit into Celsius

In this tutorial, we will discuss the concept of the“PHP code to convert Fahrenheit into Celsius”.

In this post, we will learn how to write a program to convert Fahrenheit into Celsius using the scientific equations 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 Fahrenheit into Celsius. Fahrenheit and Celsius are the measuring units in degrees as ⁰F and ⁰C  respectively.

Scientific equation Celsius = (Fahrenheit-32)*9/5

Code to Fahrenheit to Celsius

Convert Fahrenheit to Celsius

In this program, the user declares and initializes a double variable Fahrenheit as 100.00 It will be converted into Celsius, using the scientific equation in the PHP programming language.

Program 1

<?php
$fahrenheit=100.0;
$celsius=(($fahrenheit-32)*5)/9;
echo("The temperature in Celsius is: ");
$celsius=round($celsius,3);
echo(($celsius));
?>

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

The temperature in Celsius is: 37.778

 

Convert Fahrenheit to Celsius – Entered by user

In this program, the user declares the variable as Double, then the user is asked to enter a double value to Fahrenheit. The entered value will be converted into Celsius, using the scientific equation in the PHP programming language.

Program 2

<?php
$fahrenheit=readline("Enter the fahrenheit: ");
$celsius=(($fahrenheit-32)*5)/9;
$celsius=round($celsius,3);
echo("The temperature in Celsius is: ");
echo(($celsius));
?>

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

Enter the Fahrenheit: 210.1
The temperature in Celsius is: 98.944
