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.

Usage

Open the website in a web browser.
Enter a temperature value in either Celsius, Fahrenheit, or Kelvin input fields.
View the converted values automatically updated in the corresponding fields.
Reset the fields if you want to start a new conversion.

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>
  <body>
    <video id="background-video" autoplay loop muted poster="https://assets.codepen.io/6093409/river.jpg">
      <source src="./images/bg.mp4" type="video/mp4">

    <div class="container">
      <h1 class="heading">Temperature Converter</h1>
      <div class="temp-container">
        <label for="celsius">Celsius:</label>
        <input
          onchange="computeTemp(event)"
          type="number"
          name="celsius"
          id="celsius"
          placeholder="Enter Temperature"
          class="input"
        />
      </div>
      <div class="temp-container">
        <label for="fahrenheit">Fahrenheit:</label>
        <input
          onchange="computeTemp(event)"
          type="number"
          name="fahrenheit"
          id="fahrenheit"
          placeholder="Enter Temperature"
          class="input"
        />
      </div>
      <div class="temp-container">
        <label for="kelvin">Kelvin:</label>
        <input
          onchange="computeTemp(event)"
          type="number"
          name="kelvin"
          id="kelvin"
          placeholder="Enter Temperature"
          class="input"
        />
      </div>
    </div>
    <div class="footer">

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;
  }
}
