Qalculate! is a multi-purpose desktop calculator for GNU/Linux (now ported to Mac via MacPorts). It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (GTK+).

Qalculate! has now moved to GitHub (https://github.com/Qalculate). Get the latest version from http://qalculate.github.io/downloads.html.

    Outstanding! Doing physics with the this using the units conversion is great! It says Beta but aside from one minor functionality it never crashed, mislead, or failed. Since I am inclined to break things (clumsy) this is a welcome surprise. I am studying Exoplanets online and like a lot of engineering/physics fields there are a multitude of units and formulas you are supposed to "know"; well at my age I don't even bother trying to remember; just write things down. Note: Turn "Enable Denominator suffixes" off; under Mode->Unit Display I had problems and will put in a bug report. I didn't want that feature any way. Putting the gonzo pink aside the user interface is also great! I think the authors are members of 'Pink Helmet Posse' :):) i.e. look up "Gnarly in Pink" on youtube. Rather than just take from the developers, maybe I will put in scripting. Although you apparently can do equivalent things under create functions. Oh yes: the manual is at: 'http'//qalculate.sourceforge.net/gtk-manual/index.html
