Apologies if this isn’t the best place for this post, but I wasn’t sure where else to go.
The Qalculate plasmoid bundled with OpenSUSE 12.1 doesn’t appear to work properly. Unit conversions don’t seem to work. However, I’ve managed to solve the problem by downloading the plasmod source from Qalculate! Plasmoid and compiling the plasmoid, using the relevant Qalculate development library in the repositories. Given the solution seems so simple, and it would be nice to have a working version of the plasmoid, it seems like a sensible change to make to the Qalculate plasmoid for OpenSUSE.
