Range Value Format. Meters? Feet?

Figuring everything out before I actually start my mod. One thing I was wondering about is what measurement they use. For example following distance on a Carno is 400.00. Is that meters, feet, or something else. I know my Carno gets prison buddy close to my other dino’s when following so I thing the 400 is something else.

Its unreals own measurement -

1UU == 1cm

also in world settings there is a option to change the ratio in normal UE4, not sure if its there in the devkit

Ahhh ok. I see a lot of converting in my future.
