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).
We say Distance is directly proportional to time and thatâs why this represents a direct relation. A Directly Proportional Graph describes the relationship of a graph in words and mathematically. When the two measured physical quantities are plotted to form a straight line, we say they are âproportionalâ to each other.
