I think that, at least in gef 3.1.1, the only unit supported is
RulerProvider.UNIT_PIXEL.

See for example the code of in handleUnitsChanged()
org.eclipse.gef.internal.ui.rulers.RulerEditPart:

public void handleUnitsChanged(int newUnit) {
getRulerFigure().setUnit(newUnit);
if (newUnit == RulerProvider.UNIT_PIXELS)
getRulerFigure().setInterval(100, 2);
else
getRulerFigure().setInterval(0, 0);
}

Is this implemented in gef 3.2? It would be nice to implement this...

excuse me. centimeters work ok thanks to patrik. The conversion betweeen pixels and centimeters is done in org.eclipse.gef.internal.ui.rulers.RulerFigure

Now, I see that inches aren't implemented (at least in gef3.1.1).

For change ruler's units to centimeters you have to:

yourRulerProvider.setUnit(RulerProvider.UNIT_CENTIMETERS)

see the logic example :

LogicEditor.loadProperties() and org.eclipse.gef.examples.logicdesigner.rulers
