Hello Friends Today, through this tutorial, I will tell you How to Create Amps to Watts Calculator Using JavaScript with HTML? Sure, here’s an example of an Amps to Watts calculator using JavaScript with HTML:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Amps to Watts 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>Amps to Watts Calculator</h2>
<label for="amps">Enter Amperage (A):</label>
<input type="number" id="amps" placeholder="Enter amperage">
<button onclick="calculateWatts()">Calculate Watts</button>
<p id="result"></p>
<script>
function calculateWatts() {
// Get the amperage input value
const amps = parseFloat(document.getElementById('amps').value);
// Standard voltage (adjust as needed)
const voltage = 120;
// Calculate power (Watts)
const powerWatts = amps * voltage;
// Display the result
document.getElementById('result').innerHTML = `Power (Watts): ${powerWatts.toFixed(2)} Watts`;
}
</script>
</body>
</html>
In this example:
1. Users input the amperage value in the input field.
2. When the “Calculate Watts” button is clicked, the `calculateWatts()` function is called.
3. The function retrieves the amperage value, multiplies it by a standard voltage (adjust as needed), and calculates the power in Watts.
4. The result is displayed below the button.
