Do I have a correct drawing settings for scale 1:125?

Hi

Size of my land area is 100 m x 50 m and thus I have set Model Boundary as 0,0 - 100.000,50.000. I print my drawing at scale 1:125, so I set printing scale as 1.000 mm = 0.1250 units. My print is okay but am I working in correct way?

Why my drawing scale is 1=0.125 instead 1=125 :)
