Solve by Dimensional Analysis

Solve by Dimensional Analysis is the true magic of Calchemy!

Unlike the "*" and "/" operators you use to explicitly tell Calchemy where to place operands in the equation (i.e., in the numerator or denominator), the ";" operator tells Calchemy to use dimensional analysis to determine where to place operands in the equation.

For example, if you wanted to calculate the required horsepower to raise a 2000 lb elevator to the top of a 120 foot building in one minute, you could ask Calchemy to combine 2000 lb, 120 feet, and 1 minute in such a way that the equation is dimensionally correct, and then express the final result in hp, by entering:

And tapping "=".  Calchemy would respond:

Indicating the result of 7.2727273 horsepower.

Calchemy determined that the 2000 lb and the 120 feet should be in the numerator of the equation and the 1 minute should be in the denominator (arriving at the formula P = F D/T).  Additionally, Calchemy also determined that the 2000 lb was necessarily pounds force, not pounds mass.
