Convert from Kilometers to cm php script code with html

Hello Friends Today, through this tutorial, I will tell you Convert from Kilometers to centimeters php script code with html. Here's the PHP script with HTML for converting kilometers to centimeters:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Kilometers to Centimeters Converter</title>
</head>
<body>
<h1>Kilometers to Centimeters Converter</h1>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
<label for="kilometers">Enter kilometers:</label>
<input type="number" name="kilometers" id="kilometers" required>
<br>
<button type="submit" name="submit">Convert</button>
</form>
<?php
// Check if form is submitted
if (isset($_POST['submit'])) {
// Get the kilometers value
$kilometers = (float) $_POST['kilometers'];
// Conversion rate: 1 kilometer = 100,000 centimeters
$conversion_rate = 100000;
// Calculate centimeters
$centimeters = $kilometers * $conversion_rate;
// Display the result
echo "<p><b>$kilometers kilometers is equal to $centimeters centimeters.</b></p>";
}
?>
</body>
</html>

This code simplifies the conversion by directly using the conversion rate (1 kilometer = 100,000 centimeters) within the script. It avoids defining multiple units and conversion rates as in the previous example.
