-- take the number of inches-- multiply it by 0.0254-- the result is the number of meters--------------------------------------------------------- take the number of meters-- everything to the left of the decimal point represents whole meters-- take everything to the right of the decimal point-- move the decimal point two places to the right-- the result is the number of centimeters, in addition to the number of whole meters
It makes it easier to count the number of contour lines.
A contour map shows lines which connect areas equal in height. These lines are called contours and should be labelled to show the height that each contour represents. A stream flows downhill, this is due to gravity. Thus, to determine which way a stream flows, find contours, at least two, that intersect the path of the stream, then look at the heights these contours represents(their labels). The stream will flow from the contour labelled with the higher number towards the contour labelled with the lower number. PS. sometimes not all the contours are numbered, but only say every fith contour is numbered, then you can assume that all contours are equally incremented i.e. the height difference from one contour to the next stays equal.
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.

A letter that represents a number is called a variable.
It represents the number of Protons (p+) that element has in the nucleus of one atom.
