**Calchemy on iPhone!**

Finally, a revolutionary new calculator that “understands” units of measure! Calchemy is the combination of a units conversion engine and a scientific calculator that greatly simplifies real-world problem solving.

With Calchemy you get the answers to your real-world calculations in the units you want, without ever having to look up or enter a conversion factor. Just enter the numbers into a calculation along with their units of measure, Calchemy does all the necessary unit conversions for you automatically when it solves the equation. It also makes sure sure your equation is dimensionally correct.

Calchemy makes getting correct results so simple, you might find yourself calculating just for fun!

One of the most frustrating elements of real-world calculations is that units conversions are often required to get the data you have into a form that is compatible with a known physical relationship. This is a result of the widespread use of so-called "practical units" that are prevalent in almost every field of technology. With Calchemy the units are carried through calculations with conversions applied as required to deliver the answer in the units you specify. In fact, quite remarkably, in many cases a math-magical technique built into Calchemy called "Solve By Dimensional Analysis" can even derive the algebraic equation relating the parameters for you!

Calchemy is great for solving problems that deal with energy, renewable resources, power, pressure, volume, area, force, speed, distance etc. Calchemy “understands” hundreds of units of measure and many physical properties, so you can focus on the problem and not be distracted by conversions. From basic unit conversions, to complex calculations, Calchemy does them in "one line"!

Take a look at the examples below and then give Calchemy a try for yourself, you won't be disappointed, real-world problem solving has never been so easy!

For a detailed example, let's suppose we want to compute the length, on a side, of a square 10 acre parcel of land... And we want the result in feet. To start out, we know we have to take the square root of 10 acres... We begin by telling Calchemy to take the square root of 10 of something... We are building an equation in the equation line:

We then tap the "Select" button (The one with the binoculars) to use the "unit select picker" to find all of the units of area known to Calchemy... We select "acre":

Just to be sure, we can ask Calchemy to give us the details on the unit by taping on the "i" button. We see "acre" is a unit of land measure:

We click on "Done" to return to the main screen and then enter the unit in the equation line by tapping the red checkmark button. Now we add a "?" to the equation using the button on the screen. The "?" separates the expression we want to evaluate from the unit of measure that we want the result expressed in.

We want our result expressed in feet, so we then search for the unit "foot" by name, entering in the first two characters and clicking the "Search" button (again the one with the binoculars), this time to use the "unit search picker", to find all of the units known to Calchemy that begin with "fo"

We select the unit "foot" and we have a complete equation. We tap the "=" button on the screen and we are done. We see that a square of 10 acres is 660 feet on a side.

Here are some more examples of problems you can solve with Calchemy:

10 km/l ? mpg = 23.5215 mpg

35 ft * 20 meters ? acres = 0.0527224 acres

sqrt(3acres) ? ft = 361.497 ft

( 3 / (4 pi) * 1 gal )^(1/3) ? inches = 3.80634 inches

(50 ft * 30 ft * 0.75 inches/week) / (5 gal/min) ? hours/week = 2.33766 hours/week

pi * (0.25 inch)^2 ; 160 ft ; 5 gal/min ? sec = 19.5839 sec

40 gal ; 120 degF – 45 degF ; hsv_water ; 40000 btu/hr ? min = 37.5542 min

20 gal ; 2 min + 20 sec ; hcv_gasoline ? megawatts = 17.4872 megawatts

And have FUN calculating!
