Smart Convert – Currency & Unit Conversion is not just another calculator, it is a complete conversion infrastructure for WordPress sites. Designed for performance and flexibility, it handles everything from simple currency exchanges to complex, non-linear physical unit conversions (like Temperature).
Whether you run a travel blog, or a technical documentation hub, this plugin ensures your visitors see accurate conversions in a format that fits your design.
🚀 My Ambition: Premium Features for Free With this initial release, my goal is to set a new standard for what a free plugin can offer. I believe advanced tools shouldn’t be locked behind a paywall. That is why Smart Convert includes enterprise-grade features usually found only in paid versions: a Custom Unit Builder, a Template Engine, Import/Export capabilities, and Automatic Geolocation—all completely free.
<h3>🌟 Key Features</h3>
💰 Advanced Currency Engine 
* Rates: Supports 153 global currencies + cryptocurrencies (BTC, ETH, etc.). 
* Smart Geo-Location: Automatically detects visitor IP to display their local currency (powered by ipinfo.io). 
* “Spread” & Fees: Add a percentage markup (e.g., 2%) to exchange rates to simulate bank fees or retail pricing. 
* Smart Rounding: Intelligently adjusts decimals (e.g., 0 decimals for JPY, 6 decimals for BTC).
📏 Comprehensive Unit Converter 
* 105+ Built-in Units: Covers 14 categories including Length, Mass, Volume, Temperature, Pressure, Energy, Speed, and Data. 
* Bi-Directional Custom Units: Creating a unit like “Box” (e.g., 1 Box = 12 Items). The plugin automatically generates the reverse conversion logic for you. 
* Complex Math: Handles non-linear conversions (like Fahrenheit to Celsius) with precision offset calculations.
🎨 Visual & Editor Integration 
* Native Gutenberg Block: Visually configure conversions (Amount, From, To, Decimals) with a live backend preview. 
* Inline Toolbar Tool: Select any text in your post and convert it instantly using the rich text toolbar button. 
* Interactive Tooltips: Solves the common “overflow:hidden” clipping issue using a smart portal strategy to display rates on hover. 
* Template System: Design your output using placeholders like <code>{FROM}</code>, <code>{TO}</code>, <code>{RATE}</code>, and <code>{DATE}</code>.
⚙️ Performance & Workflow 
* Zero Database Bloat: Uses robust Object Caching and Transients. 
* Import/Export: Transfer your custom templates and custom units between sites via JSON. 
* Privacy First: External connections are disabled by default until explicit consent is given via the Onboarding Wizard.
