How do you change degrees to meters?
Subtract the smaller longitude from the larger one for places that are both in the Eastern or both in the Western Hemisphere. Add the longitudes if the places are in different hemispheres. Multiply the degrees of separation of longitude and latitude by 111,139 to get the corresponding linear distances in meters.

How does QGIS project data from another CRS?
What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice. To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window: In the dialog that appears, check the box next to Enable ‘on the fly’ CRS transformation.
Why does QGIS not know where Cape Town is?
You can see why this is a problem. QGIS doesn’t know where Cape Town is supposed to be – that’s what the data should be telling it. If the data tells QGIS that Cape Town is 34 meters away from the equator and that South Africa is only about 12 meters from north to south, then that is what QGIS will draw.
