JKL Unit Converter free WordPress plugin

I’m an American expat in South Korea so I find I’m constantly wanting to convert between various units of measurement for different things. My family talks to me over Skype in Fahrenheit; recipes online call for 8 ounces of something; and I always wondered what various Korean house sizes and floor plans (pyoung) actually were in square meters or square feet. Well now, I’ve created just the plugin to take care of all of those kinds of conversions. It currently includes functions for 14 different conversion formulas (like length, weight, temperature, speed, etc), but there are plans for about 20 more! (For a full list of conversion formulas and units, see the plugin NOTES section below.) This plugin was inspired by Google’s Unit Converter and includes the majority of the units listed on their website (including some extra silly ones I’ve found and a handful of Korea specific units of measurement). Requires WordPress 3.5 and PHP 5.4 or later. Special Features Provides varying levels of complexity for conversion lists (Basic – 6 types, Default – 14 types) Provides a default list of the most common units for each list, but also a checkbox to enable ALL unit types (including some obscure ones from ancient history and fiction) Lists values are dynamically controlled with JavaScript so that as soon as you change list types, the units of measurement are immediately switched (without page refresh) Notes Multiple widgets are allowed at once (on the same Post/Page) Multiple shortcodes (on the same Post/Page) are disabled – multiple shortcodes will display only ONE form On Posts/Pages with a shortcode, the widget will be disabled Planned Upcoming Features AJAX form submission to prevent page reload An Advanced List of conversion formulas – 32 types More conversion units supported Possibly allow users to select whether or
