Calculate with Qalculate on Linux
The calculator options on Linux just blows the Windows calculator away. Imagine a calculator where you can solve extremely complicated expressions, or just convert between different measurements, and you've got Qalculate.
You can use it to convert currencies based on the latest exchange rates, which the application will download for you.
You can even solve extremely complex algebra functions (this one isn't complicated, of course)
You can even use it to convert between a unix timestamp and regular dates.

Installation on Ubuntu
Open a terminal window and type in the following:
sudo apt-get install qalculate
That's pretty much it… I'd be very interested to hear any comments about really complicated calculations that you've been able to solve using this tool.


Another nice Linux calculator is Powercrunch, though I also have Qalculate installed.
Got a URL for that? Google gave me nothing.
http://qalculate.sourceforge.net/ (You may have added the habitual U after the Q when you did your Google search, but Qalculate is spelled without it.)
Thanks qajaq, but I was referring to the Powercrunch application that Jake mentioned….
I guess he meant Speedcrunch?
I use it all the time, but Qalculator seems to have more functions. Will give it a shot.
Is there any equivalent for Windows? exchange rates updates is definitely useful.
(I really want to install Linux and dual-boot it with XP but I afraid from screw up the family' computer and lost the data on the hard drive if something will go wrong..)
Oh yes Speedcrunch. I guess I wasn't thinking straight. :-[
What is that pretty blue theme you're using? Nice window borders!
The theme is actually the default KDE theme for Kubuntu.
The Qt version is shown here, but there's also a GTK version for all you GNOME, XFCE, etc. users out there.
Hi friends! I personally like Qalculate so much! IŽm using it on Windows XP right now. How? I did install andLinux on my Window$ XP! This way I can install/use Linux programs on XP, without the messing of dual-boot or emulation/virtualization. Make a Google search, youŽll find some interesting YouTube-videos about andLinux.
