Alcohol Dilution Calculator

Interactive Alcohol Dilution Calculator for OpenCart

The Alcohol Dilution Calculator module adds a fully self-contained calculator page to your OpenCart store. Customers enter their current alcohol strength, their target strength, and the volume they are working with - the module instantly returns how much water to add and the resulting total volume. All calculations apply at 20 degrees Celsius and run via AJAX so there is no page reload.

Key Features

• Calculates water volume to add and final total volume from three simple inputs
• AJAX calculation - instant results without a full page reload
• Dedicated storefront page with a configurable SEO-friendly URL (default: /moonshine-calculator)
• Per-language page title, H1 heading, description text, and usage instructions - all fields accept HTML
• Calculator page is automatically registered in sitemap.xml
• Compatible with OpenCart 2.3 and 3.x; uses Twig templates and the default theme

A Worked Example of a Custom Interactive Tool Page

This module is part of the AlexWaha OpenCart bundle - a collection of practical, niche extensions built for real store use cases. The Alcohol Dilution Calculator demonstrates how a focused interactive tool page can be delivered cleanly inside OpenCart without touching core files: a dedicated route, a Twig template, AJAX handling, sitemap integration, and multilingual admin settings all in one small, self-contained module. If your store serves a specialty audience that needs on-site calculation tools, this module shows the pattern in action.
