Not really. Distance (vector magnitude) is in unreal units, scale is unitless (in this context) - a simple multiplier. Location is a vector, each component XYZ is in unreal units. Normal is a direction vector with length of 1 uu. Rotation is in degrees but radians are used here and there, especially when you deal with physics, angular velocities, for example.
They’re the same. 1uu = 1cm
edit: When you deal with a 2D interface, you’ll be dealing with pixels rather than cm or unreal units.
