I favor the idea of renaming the right angle as the 'quad' (with milliquads,
microquads etc.) as the basis for the best choice for practical angle
measurements in SI. If you would like me to elaborate on this let me know
and I will send you a short essay on the quad.
As a matter of interest, an angle of 1 milliquad would subtend a distance of
785 millimetres at a distance of 1 kilometre.
I am confused. I get that at 1 km an angle of 1 quad would be
subtended by �/2 km, and hence a milliquad would be subtended by �/2
m = 1.571 m.
What is the diference, if any, between 1 milliquad and 0.1 grade, grad or gon?
