I need to tile a texture across a plane with updating geometry (floor fill), and I need the texture to be scaled to fit real-world dimensions in centimeters. It is a square floor tile of 50cm, and the texture size is 1024 pixels. How do I convert pixels to meters in ARKit? i know that I have to use SCNMatrix4MakeScale on the SCNMaterial diffuse.contentsTransform but not sure what properties to set to get it accurate.

What you might do is use the physical size of
SCNNodethat you are working with and determine how much squares of 50x50cm could it fit. After you get this coefficient, use it inside thecontentsTransformto achieve needed behavior. Please refer to this answer for code snippets and more hints that you might find useful.
