This paper explains the characteristics of Transverse Mercator projections, the relationship of plane grids to USGS map cells, and the reasons DRG's and other USGS digital products are projected on the UTM.
âº If two amounts are proportional, they change at the same rate so that the relationship between them does not change: 1  Weight is proportional to size. 2  How far you go is directly proportional to how fast you go (= as one thing increases, the other increases at exactly the same rate).
The relationship of the size of the parts to the whole. 1. Proportion is a matter of comparisons. 2. Proportion = the relative size of an object in comparison to another object or in comparison with some mental norm or standard.
