Unit of Scale on Eigenmodes Output

Hello everyone,

I am currently running some optimizations for a strucutural component, which I have to write an Essay about.
While looking at the eigen modes Output, this question accured:

What is the Unit displayed on the scale? It says Eigen Modes Magnitude, but does that mean the oscillation in Hz, the displacement in mm, no unit or another unit?

I appreciate any help and hints!
