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';
