Hello Friends Today, through this tutorial, I will tell you How to Write Program kW to kVA calculator using PHP with HTML? To create a kW to kVA Calculator using JavaScript and HTML, you can create a simple web page that takes the input in kilowatts (kW) and calculates the corresponding kilovolt-amperes (kVA) based on a power factor. Below is an example implementation:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>kW to kVA Calculator</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 20px;
}
label {
display: block;
margin-bottom: 8px;
}
input {
width: 100%;
padding: 8px;
margin-bottom: 16px;
box-sizing: border-box;
}
button {
background-color: #4CAF50;
color: white;
padding: 10px 15px;
border: none;
border-radius: 4px;
cursor: pointer;
}
button:hover {
background-color: #45a049;
}
</style>
</head>
<body>
<h2>kW to kVA Calculator</h2>
<label for="kW">Enter Power in kW:</label>
<input type="number" id="kW" placeholder="Enter power in kW">
<label for="pf">Enter Power Factor (optional, default is 1.0):</label>
<input type="number" id="pf" placeholder="Enter power factor" value="1.0">
<button onclick="calculateKVA()">Calculate kVA</button>
<p id="result"></p>
<script>
function calculateKVA() {
// Get the input values
const kW = parseFloat(document.getElementById('kW').value);
const powerFactor = parseFloat(document.getElementById('pf').value) || 1.0;
// Calculate kVA
const kVA = kW / powerFactor;
// Display the result
document.getElementById('result').innerHTML = `kVA: ${kVA.toFixed(2)}`;
}
</script>
</body>
</html>
In this HTML file, we have an input field for entering power in kilowatts (kW) and another input field for entering the power factor (default is set to 1.0 if not provided). When the “Calculate kVA” button is clicked, the `calculateKVA()` function is called. This function calculates the kVA value based on the entered kW and power factor and displays the result on the page.
