How do I set up Maya grid to match UE4?

I have found how to set up UDK to match Maya but I have read so much that says that UE4 grid and UU is different. What is the default UU for UE4? Thank you.

UE4 unit = 1cm, (same as Maya I believe).
Maya (and others like Blender or 3DSMax) let you choose which unit you prefer to use.
I have no problem with export from Maya 2014 using these settings:
