A small Ruby script to convert units from the command line.
convertnew <quantity> <from_unit> <to_unit>
Example :
convertnew 120 m2 pi2
Fill in the conversion table.
Use the conversion rate (ex: 1 pi2 = 0.09290304 m2) so that : 1 <from_unit> = x <to_unit>
@conversion_table = [
[ 'pi2', 'm2', 0.09290304 ],
[ 'kg', 'livre', 2.205 ],
[ 'euro', 'dollarca', 1.56 ],
[ 'pi', 'm', 0.3048 ],
[ 'in', 'm', 0.0254 ],
[ 'yd', 'm', 0.9144 ],
[ 'mi', 'm', 1609.344 ],
