Better, but not as much error checking yet. Requires Python 2.2/2.3/2.4 or newer.
PhysCalc is a unit converter and general calculator. It allows you to enter expressions like: (1 foot + 1 meter) and get your results back in inches. It is essentially a calculator with an extremely flexible user-programmable unit converter built in. You can easily define your own new units, of any dimension you like. Need to work with money? Declare a dimension "currency" with units "cent" and "dollar" and you can automatically use combined units like "cents per kilowatt hour". It's far more flexible than all other unit converters I've seen. Ideal for the physics student, or just to figure out how many teaspoons in a cup.
