You are talking here about a "gon" wich is defines as 

  1 gon = pi/200 rad

I've heard that those are used for measuring the landscape. But they are
as invalid for SI as "deg" is. And they lack the common use that "deg"
has. So we can forget them very fast. (If someone wants to experiment
with them: the standard Casio calculators can be switched into that mode
for the trig functions... I think it's called "gra" on them)

CU,
Christian
