How to convert Fahrenheit temperature to Celsius temperature in php

With the rapid development of information technology, the popularization of the Internet and the rise of e-commerce, computer technology has become one of the skills that people must master. Among them, programming skills are particularly important. And PHP is one of the most popular programming languages ​​in web development. Today, let’s talk about how to convert Fahrenheit temperature to Celsius temperature in PHP.

The difference between Fahrenheit and Celsius

First of all, we need to understand the relationship between Fahrenheit and Celsius. Fahrenheit is a thermometer created by German physicist Fahrenheit in 1724. The freezing point of water is 32 degrees and the boiling point is 212 degrees as the zero point of the temperature scale. 0°F represents the freezing point of water and 100°F represents the boiling point of water. The Celsius temperature is a thermometer temperature scale based on the freezing point and boiling point of water at 0°C and 100°C. The Celsius thermometer is divided into 100 equal parts.

Fahrenheit temperature to Celsius temperature formula

To convert Fahrenheit temperature to Celsius temperature in PHP you can use the following conversion formula:

C = (F-32) * 5 /9

Among them, C represents the converted Celsius temperature, and F represents the Fahrenheit temperature.

PHP code implementation

The following is an example of PHP code implementation:

$f = 75; // Define Fahrenheit temperature
$c = round(($f - 32) * 5 / 9, 2); // Convert to Celsius and keep two decimal places
echo "Fahrenheit" . $f . "℉ Convert to Celsius: " . $c . "℃";
?>

Code analysis:

• First define a Fahrenheit temperature $f as 75 degrees.
• Then use the above conversion formula to convert Fahrenheit to Celsius, and use the round() method to keep the result to two decimal places.
• Finally use echo to output the converted Celsius temperature.

Summary

Through the above example, we can see that it is not difficult to convert Fahrenheit temperature to Celsius temperature. Just follow the conversion formula to calculate. In PHP, we can use round() method to preserve the number of decimal places. In addition, in actual development, we can encapsulate the conversion function so that we can call it more conveniently.

When learning programming, you must not only master the syntax of the programming language, but also learn how to solve practical problems. The example of converting temperatures from Fahrenheit to Celsius is a good practice. I hope this article will be helpful to everyone's study.
