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 [ed.: as of when this was written in the 1990s]. Ideal for the physics student, or just to figure out how many teaspoons in a cup.
