blaconvert - Java program for converting units of measurement and currency using Google APIs
by blatech
Copyright 2011 Joe Robinson <joe@lc8n.com>
based on code by Jamie Walters <jagw@jagw.co.uk>
based on code by Joe Robinson <joe@lc8n.com>
Version 1.31
CHANGELOG
1.0 - First version
1.1 - Allow units with more than one word eg "light year"
- Added "same unit" error
- Ensure standard imperial measurements are used for some units - google defaults to US
1.2 - Replace crazy non unicode spaces with commas
1.21 - Added quart to imperial measurements
1.3 - Added support for currency symbols
1.31 - Trying to add euro (probably won't work)
TODO
- Raw output option - result only with no spaces/commas/units
