Elevation Calculator

Understanding elevation is essential for outdoor enthusiasts, geographers, hikers, bikers, and engineers. Whether planning a hiking trail, assessing a biking route, or analyzing terrain for construction, accurate elevation data is critical. The Elevation Calculator is a versatile online tool that allows you to measure elevation gain, slope/grade percentage, altitude based on pressure, and even determine elevation from coordinates.

This tool makes complex calculations simple, providing instant results for a variety of practical applications.

What Is the Elevation Calculator?

The Elevation Calculator is an online utility designed to measure elevation and related metrics. It supports multiple calculation types:

  1. Elevation Gain: Determine the vertical distance ascended over a specific route.
  2. Grade/Slope %: Calculate the steepness of a trail, road, or incline.
  3. Altitude & Pressure: Estimate elevation based on atmospheric pressure.
  4. From Coordinates: Find elevation for a specific location using latitude and longitude.

By offering multiple calculation methods, this tool serves hikers, bikers, surveyors, civil engineers, and geographic enthusiasts alike.

How to Use the Elevation Calculator

Using the tool is straightforward. Follow these steps:

Step 1: Select Calculation Type

From the Calculation Type dropdown, select one of the following options:

  • Elevation Gain – For total vertical ascent of a route.
  • Grade/Slope % – To determine incline steepness.
  • Altitude & Pressure – For estimating height from barometric pressure.
  • From Coordinates – Find elevation using GPS coordinates.

Step 2: Enter Required Data

The required input depends on the selected type:

  • Elevation Gain: Enter the start and end elevation values.
  • Grade/Slope %: Input vertical rise and horizontal distance.
  • Altitude & Pressure: Enter atmospheric pressure and temperature (optional for accuracy).
  • From Coordinates: Input latitude and longitude of the location.

Step 3: Click Calculate

After entering all inputs, click Calculate. The calculator will instantly display results:

  • Elevation Gain: Total ascent in feet or meters.
  • Grade/Slope %: Steepness percentage of the incline.
  • Altitude: Estimated elevation above sea level.
  • Elevation from Coordinates: Height of the point at given GPS coordinates.

Step 4: Reset if Needed

Use the Reset button to clear all inputs and start a new calculation.

Example: Using the Elevation Calculator

Example 1: Elevation Gain

Suppose you hike a trail starting at 1,200 ft and ending at 2,500 ft:

  1. Select Elevation Gain.
  2. Input 1,200 as start elevation and 2,500 as end elevation.
  3. Click Calculate.

Result: Total elevation gain = 1,300 ft.

Example 2: Grade/Slope %

You want to know the slope of a hill with a rise of 200 ft over a horizontal distance of 1,000 ft:

  1. Select Grade/Slope %.
  2. Input rise = 200 ft, run = 1,000 ft.
  3. Click Calculate.

Result: Grade = 20%.

Example 3: Altitude & Pressure

You measure a pressure of 950 hPa at a hiking location:

  1. Select Altitude & Pressure.
  2. Enter 950 hPa.
  3. Click Calculate.

Result: Estimated elevation = 518 meters above sea level.

Example 4: From Coordinates

You want to find the elevation at 40.7128° N, 74.0060° W (New York City):

  1. Select From Coordinates.
  2. Enter latitude = 40.7128 and longitude = -74.0060.
  3. Click Calculate.

Result: Elevation ≈ 10 meters above sea level.
