This is a great program, like a fast Google Calculator/Wolfram Alpha but with more units that runs on your desktop, with more calculations and more up-to-date currencies than GNU Units.
I wish someone would port it to Windows.
Some of the things it can do:
@endolith
Qalculate! has already been ported to Windows, there is also a portable version (since version 3.1.0), see releases at GitHub (https://github.com/Qalculate/qalculate-gtk/releases).

Presents history and symbolic calculations.
It's responsive, intuitive, has the best command line interface of any computer algebra system I've ever used, and continues to be developed at a very fast pace with new features arriving every 2-3 months.
A very professional piece of software. It could be $20 no problem. Contribute people what you can, either code or money to the programmers.
Probably the most advanced calculator app I have ever used. With many additional features like currency and unit conversion, huge number of predefined functions and constants, contains even a simple periodic table. And it's fast, relatively small and open source (written in C++)!
