Percentage error of a guess at a position, and the actual position.

samedi 31 mai 2014

How do I calculate the percentage error between a guess of a position in 3D space, and the actual position. For example, if I am allowed an error of 100mm in the x, y, and z directions, in a 5m x 4m x 3m volume, what is the maximum percentage error allowed?



Can I just do:



[itex]\frac{100*10^{-3}^3}{5*4*3}=1.67*10^{-5}%[/itex]





Is this correct? It just seems a bit small to me.



Thanks!

(0.1^3)/(5*4*3)=0.0000167%
