Using metres in location transforms

[This][1] lighting tutorial shows metres being used to determine the location of objects within the world (Example picture below). How would I achieve this? I would like to follow the tutorial, but have no idea how the metres relate over to whatever UE4 uses by default.

1UU(Unreal Unit) = 1cm
100UU = 1m

Cheers! Any idea how to get that to display like in the picture, though? Just a curiosity thing more than anything, I can’t find it in settings at all.

I looked into it but I don’t know. I think it was just an old build of the engine

Yeah, I was starting to figure as much… cheers for the answer, anyway!
