Unit Converter

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.

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.

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';
