Hello Friends Today, through this tutorial, I will tell you How to Write Program kW to VA (Volt-Ampere) calculator using JavaScript with HTML? Below is an example of a kW to VA (Volt-Ampere) calculator implemented using JavaScript with HTML:

<h2>kW to VA Calculator</h2>
<label for="power">Enter Power (kW):</label>
<input type="number" id="power" placeholder="Enter power in kW">
<button onclick="calculateVA()">Calculate VA</button>
<p id="result"></p>
<script>
function calculateVA() {
// Get the power input value in kW
const powerKW = parseFloat(document.getElementById('power').value);
// Convert kW to VA
const powerVA = powerKW * 1000; // 1 kW = 1000 VA
// Display the result
document.getElementById('result').innerHTML = `Power (VA): ${powerVA} VA`;
}
</script>
</body>
</html>
This HTML file includes an input field for entering power in kilowatts (kW), a button to trigger the calculation, and a result paragraph to display the calculated power in volt-amperes (VA). When the button is clicked, the `calculateVA` function is called, which performs the conversion from kW to VA and updates the result on the page.
