Scaled Odds Ratio and Interpretation

I'm trying to calculate a scaled odds ratio for an analysis that I'm working on. I have two types of independent variables in the model: 1) percentage data (0-100%) and 2) Euclidean distance to nearest roads. The distance to road data was collected in 1-meter increments; therefore, the odds ratio below for roads_eucl would read for every 1 unit change in distance to nearest road, I would expect a 0.3% decline in use. This doesn't seem very informative given the scale of 1-meter. How would you scale the distance to represent every 10-meters or every 100-meters? In addition, how would you interpret the odds ratio for the percentage data? For example, would you state: for every 1-unit increase in MPHW_Perc, I would expect a 0.8% increase in use? This seems low; therefore, would you scale the percentage somehow? Thanks for the help!

                  OR     2.5 %    97.5 %
