How to Use the HCP Height Calculator
Using the HCP Height Calculator is simple and intuitive. The primary parameters required for the calculation are the angle of elevation and the horizontal distance from the object whose height you want to determine.
Step-by-Step Guide:
- Enter the Angle of Elevation:
- The angle of elevation is the angle formed by the line of sight from your eyes (at the point of observation) to the top of the object you are measuring. This angle is typically measured in degrees.
- Enter the Distance from the Object:
- Input the horizontal distance between you and the base of the object. This is the straight-line distance measured along the ground from where you are standing to the base of the object.
- Click “Calculate”:
- Once both parameters are entered, click the “Calculate” button to get the height of the object.
- View the Result:
- The result will display the height of the object, calculated using trigonometric principles.
Formula for HCP Height Calculation
The height calculation in the HCP Height Calculator is based on trigonometry, specifically using the tangent function. The formula for height calculation is:
HCP Height Formula:
iniCopyEditHeight = Distance × tan(Angle of Elevation)
Where:
- Height is the height of the object you are trying to measure.
- Distance is the horizontal distance between you and the base of the object.
- Angle of Elevation is the angle between the ground and your line of sight to the top of the object, measured in degrees.
Example Calculation:
Let’s go through an example to illustrate how this formula works in practice.
Example 1:
Suppose you are standing 50 meters away from a building and you measure the angle of elevation to the top of the building to be 30 degrees. To calculate the height of the building, you would use the formula:
iniCopyEditHeight = 50 meters × tan(30 degrees)
Using a scientific calculator to find the tangent of 30 degrees, we get:
iniCopyEditHeight = 50 meters × 0.577
Height = 28.85 meters
So, the height of the building is approximately 28.85 meters.
