How do you measure the slope?
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.

How do you measure elevation?
An easy-to-remember equation for finding change in elevation as a decimal is “rise over run,” meaning the rise (the change in vertical distance) divided by the run (the change in horizontal distance). As an example, let's say the rise is 2 and the run is 6. So, you'd take 2 over 6 (or 2/6) to get .

How is slope measured?
Slope generally is measured with an instrument called a clinometer. When sighting through a clinometer, the measuring line is placed on the target, and %slope is read from the scale. Both eyes are open, as one eye reads the scale, and the other eye sights on the target (Figure 1.7).
How to measure %slope?
First determine where 0 percent slope (eye level) is on your partner. Then use this point as the target when taking readings with the clinometer (Figure 1.8). In this way, you will be measuring parallel to the slope, mirroring the land.
How many scales does a clinometer have?
A clinometer generally has two scales. In this figure, the scale on the left measures %slope. The scale on the right measures topographic slope (see Chapter 2). Also note the “plus” signs below zero on each scale, and the “minus” signs above zero on each scale.

How to find the inclination of two parallel lines?
Consider two parallel lines given by l1 l 1 and l2 l 2 with inclinations α and β respectively. For two lines to be parallel their inclination must also be equal i.e. α=β. This results in the fact that tan α = tan β. Hence, the condition for two lines with inclinations α, β to be parallel is tan α = tan β.

What is a carpenter's level?
A carpenter’s level is a device that can be used to measure slope. It consists of a rectangular board, called the “leveling head,” mounted on two metal rods or tubes at right angles to each other and joined by springs so that it can pivot freely in any direction. In addition, the leveling head has a vial of liquid (usually mercury) that indicates when the surface being measured is horizontal.

How to measure downslope?
Measure your distance to the up-angle reference point you created from the left side of your carpenter’s level. This will be in feet on one end and inches on the other – since you’re measuring slope, this is your downslope reading, while points closer to zero degrees are considered positive slopes (uphill).
