Differences btw X-Y Plane and R-Z Plane

[Skyeagle]

Hi guys,

While working with coordinates, I notice that for those that deal with axi-symmetry, the R-Z plane is used.

May I know what's the difference between the XY plane and the RZ plane?

I mean is 1 unit along the X-axis the same as 1 unit along the R axis or is there a conversion?

Thanks and Best Rgds

Hi Skyeagle!

… I mean is 1 unit along the X-axis the same as 1 unit along the R axis or is there a conversion?

I assume you're talking about cylindrical coordinates, r z and theta (or phi)?

Yes, the unit r vector is the same length as the unit x y or z vector.
