I am working with a German KUKA robot and digging deep into the configuration files. One set of config variables sets the software joint angle limits of the arm. I can see from the value and the actual function of the arm that it is clearly a assignment of degrees. But the German-language comments state "GRAD". Confusing.

Grad (100 grads in right angle) was (and maybe still is) used in surveying at least in some countries in the Europe.
In Russian it means degree, same as in German.
