Calchemy 1.0

the author of this app says:

Calchemy is a conversion calculation program that allows users to perform analysis, dimensional arithmetic and many other conversions using standard units.

Features:

• Transparent unit conversions and calculations
• Automatic dimensional analysis
• Database with hundreds of units
• Calculation history (like a paper tape readout)
• Scientific Operations (if MathLib is installed)

Though I consider myself good at Math, I had a hard time understanding this application. It does the basic math that everyone uses calculators for, plus tons of extra functions that can be done if you take the time to read the directions and look at the examples on the homepage.
