Hello Friends Today, through this tutorial, I will tell you How to Write Program kW to VA (kilowatts to volt-amperes) calculator using PHP with HTML? To create a kW to VA (kilowatts to volt-amperes) calculator using JavaScript with HTML, you can follow this example:
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 VA 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 VA Calculator</h2>
<label for="kw">Enter Power in kW:</label>
<input type="number" id="kw" placeholder="Enter power in kW">
<button onclick="convertKWtoVA()">Convert</button>
<p id="result"></p>
<script>
function convertKWtoVA() {
// Get the input value (power in kW)
const kw = parseFloat(document.getElementById('kw').value);
// Convert kW to VA (Assuming power factor of 1)
const va = kw * 1000;
// Display the result
document.getElementById('result').innerHTML = `Power in VA: ${va} VA`;
}
</script>
</body>
</html>
This HTML file contains an input field for entering the power in kW, a button to trigger the conversion, and a paragraph to display the result in VA.
When the button is clicked, the `convertKWtoVA` function is called, which takes the kW input value, multiplies it by 1000 (since 1 kW is equal to 1000 VA), and then displays the result in the designated paragraph.
