# Introduction to Calchemy

Why Calchemy?

The best way to get to know about Calchemy is to look through a few
examples and then try some problems yourself...

### Here are some examples...

### And some info about how to use UNCALC...

### VERY IMPORTANT:

- Calchemy works only with quantity equations.
if you include unit conversion factors like the ones you may find in
numeric equations, Calchemy will produce an
**incorrect** result!

- Be sure you enter all the
**dimensionless parameters** of an equation, like **pi**
or **(4/3)** correctly! Because these parameters are dimensionless,
Calchemy is unable to determine if they are required, and cannot provide error detection for them.

- When in Doubt, use parenthesis. Note that 2 ft^2 is NOT the same
as (2 ft)^2 and 1/2 ft is not the same as (1/2) ft.

- If it's important,
**ALWAYS CHECK YOUR RESULTS**.
