## Description

This plugin detects units of measurement (e.g. “10 lbs”) and will add the metric
or non-metric equivalent (e.g. “4.5 kilograms”). The converted measurement can be
added in several ways:

 * as a mouse-over, or
 * in brackets after the original measurement, e.g. “10 lbs (4.5 kilograms)”.

It is useful if you use lots of measurements and are writing for an international
audience.

#### Currently Supported Conversions

 * Celsius Fahrenheit
 * Centimetres inches
 * Grams ounces
 * Kilograms pounds
 * Kilometres miles
 * Kilojoules (food) calories
 * Litres gallons
 * Metres feet
 * Millilitres fluid ounces

Note that these non-metric units are in [US customary units](http://en.wikipedia.org/wiki/United_States_customary_units).

### Bugs

 * Converted measurements will always be written in their canonical/long name, e.
   g. ‘kilograms’ instead of ‘kg’.
 * Cannot handle quoted aliases (e.g. 5′ or 9″) or composite measurements, e.g. 
   5’9″.

To report any bugs please do so from the [plugin homepage](http://miknight.com/projects/unit-converter/).

### Plans

 * An options page to configure various aspects of the plugin.
 * Auto-detection for which measurement abbreviation to use for the converted unit(
   lbs -> kg, pounds -> kilograms).
 * An option to use Imperial measurements as distinct from US customary units.

## Installation

 1. Upload the `unit-converter/` directory to the `/wp-content/plugins/` directory,
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.

## FAQ

  The mouseover method is the default. How do I use the parentheses?

As there is no options page (yet), you will need to edit the `/wp-content/plugins/
unit-converter.php` file around line 31 and change:

    ```
    $display_mode = 'mouseover';
    ```

to

    ```
    $display_mode = 'parentheses';
    ```
