Build a Temperature Converter Website
Introduction
Hello, fellow developers! I'm excited to share my latest project: a practical Temperature Converter. This project is perfect for those looking to enhance their JavaScript skills by working with user inputs, performing conversions, and dynamically updating the DOM. Whether you're a beginner or an experienced developer, this Temperature Converter is a great project to understand the basics of unit conversion.
Project Overview
The Temperature Converter is a web-based application that allows users to easily convert temperatures between Celsius, Fahrenheit, and Kelvin. This project demonstrates how to create an interactive user interface, handle calculations, and provide real-time feedback to the user.
Features
- User-Friendly Interface: Simple and intuitive design for ease of use.
- Real-Time Conversion: Instantly converts temperature values as you input them.
- Responsive Design: The layout adapts to different screen sizes, providing a seamless experience on both desktop and mobile devices.
- Multiple Unit Support: Converts between Celsius, Fahrenheit, and Kelvin.
Technologies Used
- HTML: Structures the web page and input elements.
- CSS: Styles the interface, ensuring a clean and responsive design.
- JavaScript: Handles the conversion logic and updates the temperature values in real-time.
Project Structure
Here's a quick look at the project structure:
Temperature-Converter/ ├── index.html ├── styles.css └── script.js
- index.html: Contains the HTML structure for the Temperature Converter.
- styles.css: Includes CSS styles to enhance the appearance of the converter.
- script.js: Manages the conversion logic and dynamic updates.
Installation
To get started with the project, follow these steps:

Code Explanation
HTML
The index.html file provides the basic structure of the Temperature Converter, including the input fields for Celsius, Fahrenheit, and Kelvin. Here’s a snippet:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Temperature Converter</title>
<link rel="stylesheet" href="./style.css" />
<script src="./script.js" defer></script>
</head>

CSS
The styles.css file styles the Temperature Converter, providing a clean and responsive layout. Here are some key styles:
body {
margin: 0;
background: url(./images/bg.mp4);
min-height: 100vh;
display: flex;
justify-content: center;
flex-direction: column;
align-items: center;
font-family: monospace;
color: white;
}
.container {
background: #202124;
padding: 20px;
box-shadow: 0 4px 10px rgba(0, 0, 0, 0.3);
border-radius: 10px;
width: 85%;
max-width: 450px;
min-width: 350px;
display: flex;
flex-direction: column;
align-items: center;
}
.heading {
font-size: 32px;
}
.temp-container {
width: 100%;
padding: 15px;
font-weight: bold;
font-size: 18px;
}
.input {
width: 220px;
font-family: monospace;
padding: 5px;
float: right;
outline: none;
background: white;
border-color: white;
border-radius: 5px;
color: black;
font-size: 18px;
}
.input::placeholder {
color: gray;
}
#background-video {
width: 100vw;
height: 100vh;
object-fit: cover;
position: fixed;
left: 0;
right: 0;
top: 0;
bottom: 0;
z-index: -1;
}
.footer {
margin-top: 200px;
text-align: center;
}
JavaScript
The script.js file handles the conversion logic, updating the temperature values based on user inputs. Here’s a snippet:
const celsiusEl = document.getElementById("celsius");
const fahrenheitEl = document.getElementById("fahrenheit");
const kelvinEl = document.getElementById("kelvin");
function computeTemp(event) {
const currentValue = +event.target.value;
switch (event.target.name) {
case "celsius":
kelvinEl.value = (currentValue + 273.32).toFixed(2);
fahrenheitEl.value = (currentValue * 1.8 + 32).toFixed(2);
break;
case "fahrenheit":
celsiusEl.value = ((currentValue - 32) / 1.8).toFixed(2);
kelvinEl.value = ((currentValue - 32) / 1.8 + 273.32).toFixed(2);
break;
case "kelvin":
celsiusEl.value = (currentValue - 273.32).toFixed(2);
fahrenheitEl.value = ((currentValue - 273.32) * 1.8 + 32).toFixed(2);
break;
default:
break;
}
}
