hi,

this is quite natural and you are on the good track. The odds ratio tells us how the odds change if we change the X by one unit. Imagine we look at odds of heart attack vs. weight -the odds will definitely be greater if we measure the weight in 50 kg units as when we measure in grams (i.e the odds of a heart attack by a weight increase of 50kg vs. a weight increase of 1 g)
