looking for a calculator convertor

[erockvr6]

im lookin for a simple calc that will conver feet > meters, gallons > cups, liters > gallons and stuff like that. All the ones ive seen are way too complex and just too much for what i need. I used to have a palm treo 650 and it had the best calc. Taken from Treonauts: http://blog.treonauts.com/2005/04/a_very_calculat.html

Using the conversion calculators:
For example, to perform a conversion from 32 degrees centigrade to Farenheit simply type the number 3 and 2 in the calculator pad, then press degreeC then degreeF and up pops the answer. The same process applies for all other conversions.

• Length: Length conversion for metric and English values.
• Area: Area conversions for metric, traditional and English values.
• Volume: Volume conversion for metric and English values.

Im just lookin for something with very simple drop down menus or something simple like that. any help is appreciated!!
