CC ↔ HP Converter

CC ↔ HP Converter

In this article, we'll break down the code behind a CC ↔ HP (Cubic Centimeters ↔ Horsepower) converter. This simple yet practical tool helps users convert between two essential units for vehicles and engines. We will walk through the entire code, explain each part in detail, and explore the logic behind the CC ↔ HP conversion. If you're a developer, you’ll appreciate the logic, structure, and the opportunity to improve the code!

But before we dive in, test the code yourself by clicking on the link below and trying the calculator for yourself. 🚀

Key Features of the CC ↔ HP Converter:

• Conversion Factor: A customizable factor that determines how CC and HP are related.
• Conversion Type: The ability to switch between converting from CC to HP and vice versa.
• Interactive Inputs: Two input fields that are shown based on the selected conversion type.
• Error Handling: Messages that guide users to enter valid values.

Detailed Breakdown of the Code

1. HTML Structure:

The HTML part of the code defines the structure of the CC ↔ HP Converter interface.

    <div class="cc-hp-calculator-container">
      <h2 class="cc-hp-calculator-header">CC ↔ HP Converter 🚗⚡</h2>
      <!-- Conversion Factor -->
      <div class="cc-hp-input-group" id="conversion-factor-group">
        <label for="conversion-factor">Conversion Factor (e.g., 15 CC = 1 HP) ⚙️:</label>
        <input type="number" id="conversion-factor" value="15" />
      </div>
      <!-- Conversion Type -->
      <div class="cc-hp-input-group" id="conversion-type-group">
        <label for="conversion-type">Conversion Type 🔄:</label>
        <select id="conversion-type" onchange="toggleInputs()">
          <option value="ccToHp">CC to HP 🚗 → ⚡</option>
          <option value="hpToCc">HP to CC ⚡ → 🚗</option>
        </select>
      </div>
      <!-- Input for CC -->
      <div class="cc-hp-input-group" id="cc-input-group">
        <label for="cc-input">Enter CC 📏:</label>
        <input type="number" id="cc-input" placeholder="e.g., 150" />
      </div>
      <!-- Input for HP -->
      <div class="cc-hp-input-group" id="hp-input-group" style="display: none;">
        <label for="hp-input">Enter HP ⚡:</label>
        <input type="number" id="hp-input" placeholder="e.g., 10" />
      </div>
      <!-- Convert Button -->
      <button id="convert-button" class="cc-hp-convert-button" onclick="convert()">🔍 Convert</button>
      <!-- Result -->
      <p id="result-display" class="cc-hp-result-display"></p>
      <!-- Error Message -->
      <div id="error-message" class="cc-hp-error-message"></div>
    </div>

- Conversion Factor Input: This input allows users to specify the conversion factor, which defaults to 15 CC = 1 HP.

- Conversion Type Selector: This dropdown lets users switch between CC to HP and HP to CC conversions.

- CC and HP Input Fields: Depending on the selection in the dropdown, the relevant input field (either for CC or HP) will be displayed for user input.

- Convert Button: The button that triggers the conversion when clicked.

- Result Display: A place to show the result of the conversion.

- Error Message: This is where error messages will be displayed if the user enters invalid data.

2. CSS Styling:

The styles provide a clean and user-friendly design for the converter. Here's the key CSS used for the layout:

    .cc-hp-body {
      font-family: Arial, sans-serif;
      text-align: center;
      padding: 20px;
      background-color: #f4f4f4;
    }

    .cc-hp-calculator-container {
      max-width: 400px;
      margin: 0 auto;
      padding: 20px;
      border: 1px solid #ccc;
      border-radius: 10px;
      background: #fff;
    }

- General Styling: The overall page uses a light background with centered text and a clean, minimal design.

- Calculator Container: The container is centered with a fixed width of 400px and includes padding for spacing.

- Button and Inputs: These are styled to be large and easy to interact with, with hover effects for the button.

3. JavaScript Functions:

This is where the real magic happens. The JavaScript functions handle user input, calculate the conversion, and display the result.

toggleInputs Function:

This function shows and hides the appropriate input fields based on the selected conversion type (CC to HP or HP to CC).

    function toggleInputs() {
      const conversionType = document.getElementById("conversion-type").value;
      const ccInputGroup = document.getElementById("cc-input-group");
      const hpInputGroup = document.getElementById("hp-input-group");

      if (conversionType === "ccToHp") {
        ccInputGroup.style.display = "block";
        hpInputGroup.style.display = "none";
      } else {
        ccInputGroup.style.display = "none";
        hpInputGroup.style.display = "block";
      }
    }

- Logic: If the user selects "CC to HP," the CC input field will be shown. If they select "HP to CC," the HP input field will appear instead.

convert Function:

This function performs the conversion based on the input values and conversion factor.

    function convert() {
      const conversionFactor = parseFloat(document.getElementById("conversion-factor").value);
      const conversionType = document.getElementById("conversion-type").value;
      const errorMessage = document.getElementById("error-message");
      const resultDisplay = document.getElementById("result-display");

      // Clear previous error and result
      errorMessage.textContent = "";
      resultDisplay.textContent = "";

      if (conversionType === "ccToHp") {
        const ccValue = parseFloat(document.getElementById("cc-input").value);
        if (isNaN(ccValue) || ccValue <= 0) {
          errorMessage.textContent = "Please enter a valid CC value greater than 0.";
          return;
        }
        const hpValue = ccValue / conversionFactor;
        resultDisplay.textContent = `${ccValue} CC is approximately ${hpValue.toFixed(2)} HP.`;
      } else if (conversionType === "hpToCc") {
        const hpValue = parseFloat(document.getElementById("hp-input").value);
        if (isNaN(hpValue) || hpValue <= 0) {
          errorMessage.textContent = "Please enter a valid HP value greater than 0.";
          return;
        }
        const ccValue = hpValue * conversionFactor;
        resultDisplay.textContent = `${hpValue} HP is approximately ${ccValue.toFixed(2)} CC.`;
      }
    }

- Logic: It first retrieves the conversion factor and the selected conversion type. It then checks if the user has entered valid values and calculates the result based on the formula (CC / conversionFactor\ for CC to HP, HP \* conversionFactor\ for HP to CC).

Suggestions for Improvement:

While the code works great as is, there are always ways to improve and enhance the functionality. Here are a few ideas:

• Add unit conversion support: Allow users to convert other units (e.g., Liters to CC).
• Validation Enhancements: Add checks for extreme values or very large inputs.
• Mobile optimization: Ensure the layout works smoothly on smaller screens.
• Error Message Improvements: Provide more descriptive error messages for better user experience.
