# What does two to one slope mean

One way to express slope is as a percentage. Slope percentage is calculated in much the same way as the gradient. Essentially, east-west slope is estimated as the difference between the sums of the elevations in the first and third columns of the 3 x 3 matrix.

To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. This means that for every 4 units that the line rises, it runs 1 unit. Slope gradients are written as Y: Based on this, the slope can be expressed as a ratio.

Locate two points on a graph. Subscribe to the Archtoolbox Newsletter: X, where Y is a single unit in rise and X is the run.

However, we have seen some jurisdictions that allow a maximum cross slope of 1: Express rise to run as a ratio. How to Find Slopes. You can calculate slope on a contour map by analyzing the spacing of the contours.
