6.2.1: The Uses of a Clinometer. Many professions use clinometers. Some use the clinometer to measure heights while others use clinometers to measure the slope or gradient of an incline. The following are examples of some uses of clinometers.

In their fieldwork, Geologists use clinometers to determine the height of an object (eg: a tree or a mountain) by using the formula:
Height = H + D tanA
H = height of the clinometer to the ground
D = distance of the clinometer to the object
A = angle taken from clinometer reading

Skiers and winter hikers use a clinometer as a safety device.
Snow covered slopes angled between 25 and 45 have a higher risk of avalanches and would therefore be avoided.

Sight clinometers are used to determine the height of clouds. Sailors can use them to predict possible dangers from storms.
These were more commonly used before, the more accurate, satellite weather monitors were invented.

Inclinometers (another name for a clinometer) are used in cave surveying. The clinometer helps to measure the depth of the cave and horizontal distances throughout the cave. This helps surveyors to create a map of the cave.
Digital clinometers can be used to assess the conditions of sidewalks and roads.
Appropriate slopes of roads and sidewalks are necessary for:
- road safety.
- appropriate runoff of rain.
- accessibility for pedestrians with special needs.
