Hello Friends Today, through this tutorial, I will tell you How to Create kVA to kW calculator using JavaScript with HTML? To create a kVA to kW calculator using JavaScript with HTML, you can follow this example. Remember that the conversion from kVA (apparent power) to kW (real power) depends on the power factor, which we’ll assume to be 0.8 for this example.

<h2>kVA to kW Calculator</h2>
<label for="kva">Enter kVA:</label>
<input type="number" id="kva" placeholder="Enter kVA">
<button onclick="calculateKW()">Calculate kW</button>
<p id="result"></p>
<script>
function calculateKW() {
// Get the kVA input value
const kVA = parseFloat(document.getElementById('kva').value);
// Power factor (assuming 0.8)
const powerFactor = 0.8;
// Calculate real power (kW) using the formula: kW = kVA * power factor
const kW = kVA * powerFactor;
// Display the result
document.getElementById('result').innerHTML = `Real Power (kW): ${kW.toFixed(2)} kW`;
}
</script>
</body>

In this HTML file, there’s an input field for entering the kVA value, a button to trigger the calculation, and a paragraph to display the calculated real power in kW. When the button is clicked, the `calculateKW` function is called. This function retrieves the kVA input value, multiplies it by the power factor (0.8 in this case), and displays the result on the page.
