Elevation Calculator

Measuring elevation is essential in many fields — from outdoor adventures like hiking and cycling to construction, surveying, and academic studies. The Elevation Calculator is a user-friendly online tool designed to help you calculate elevation gain, total elevation, slope percentage, and slope ratio based on horizontal distance and angle of elevation.

Whether you’re planning a mountain hike, assessing land for construction, or simply learning about slopes in geometry, this calculator makes the process quick and accurate.

How the Elevation Calculator Works

The tool uses simple trigonometry formulas to provide precise elevation data.

• Elevation Gain = Horizontal Distance × tan(Angle of Elevation)
• Total Elevation = Initial Elevation + Elevation Gain
• Slope (%) = Rise ÷ Run × 100
• Slope (ratio) = 1 : (Run ÷ Rise)

By entering a few values, you instantly get all relevant elevation results in your preferred units (meters or feet).

Step-by-Step Guide: How to Use the Elevation Calculator

Here’s a simple walkthrough:

1. Enter Horizontal Distance
   • Input the distance you plan to cover.
   • Choose your unit: meters, kilometers, feet, or miles.
2. Input the Angle of Elevation (°)
   • Provide the slope’s angle in degrees (between 0.01° and 89.99°).
3. Add Initial Elevation (Optional)
   • If you’re starting from a specific elevation point, enter that value.
   • Select unit (meters or feet).
   • If left blank, it assumes 0.
4. Select Output Unit
   • Decide if you want results in meters or feet.
5. Click “Calculate”
   • The progress bar will load, and results will appear shortly.
6. View Results
   • Elevation Gain
   • Total Elevation
   • Slope (%)
   • Slope (ratio)
7. Additional Actions
   • Copy Results to clipboard
   • Share Results via device sharing options
8. Reset Anytime
   • Click Reset to clear inputs and start over.

Practical Example

Let’s say you’re hiking up a hill:

• Horizontal Distance: 500 meters
• Angle of Elevation: 10°
• Initial Elevation: 100 meters
• Output Unit: Meters

Calculation:

• Elevation Gain: 500 × tan(10°) ≈ 88.2 m
• Total Elevation: 100 + 88.2 = 188.2 m
• Slope (%): tan(10°) × 100 ≈ 17.63%
• Slope Ratio: 1:5.67

So, after hiking 500 meters, you would reach a total elevation of 188.2 meters with a slope of 17.63%.
