VA to kW Calculator Using JavaScript HTML With Example

Hello Friends Today, through this tutorial, I will tell you How to Write Program VA to kW calculator using PHP with HTML? Sure, I can provide you with a simple example of a VA to kW calculator using HTML and JavaScript. Here’s a basic implementation:


<!DOCTYPE html>
<html lang="en">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>VA to kW Calculator</title>
input[type="number"] {
width: 100px;
margin-bottom: 10px;
<h1>VA to kW Calculator</h1>
<label for="va">Enter VA (Volt-Ampere):</label>
<input type="number" id="va" min="0">
<button onclick="calculate()">Calculate</button>
<label for="kw">Result (kW):</label>
<input type="text" id="kw" readonly>

function calculate() {
var va = document.getElementById("va").value;
var kw = va / 1000;
document.getElementById("kw").value = kw.toFixed(2);

This HTML file contains a simple form with an input field for the user to enter the VA (Volt-Ampere) value. Upon clicking the “Calculate” button, it triggers a JavaScript function that calculates the corresponding kW (kilowatt) value using the formula kW = VA / 1000. The result is then displayed in another input field.
