Enter the rise and run in inches into the calculator to determine the construction grade as a percentage. The grade represents the steepness of a slope, which is important for various construction and engineering projects.

Construction Grade Formula

The following formula is used to calculate the construction grade:

Grade (percent) = (Rise / Run) * 100

Variables:

  • Rise is the vertical change in height (inches)
  • Run is the horizontal distance (inches)
  • Grade is the slope expressed as a percentage (%)

To calculate the construction grade, divide the rise by the run and then multiply by 100 to convert it to a percentage.

What is Construction Grade?

Construction grade, also known as slope, is the measure of the steepness or incline of a surface. It is typically expressed as a percentage and is calculated by dividing the rise (vertical change) by the run (horizontal distance) and then multiplying by 100. Understanding the grade is crucial for ensuring proper drainage, road safety, and the stability of structures.

How to Calculate Construction Grade?

The following steps outline how to calculate the Construction Grade.


  1. First, measure the rise (vertical change) in inches.
  2. Next, measure the run (horizontal distance) in inches.
  3. Use the formula: Grade (%) = (Rise / Run) * 100.
  4. Finally, calculate the Construction Grade as a percentage.
  5. After inserting the measurements and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following measurements as an example problem to test your knowledge.

Rise (vertical change) = 6 inches

Run (horizontal distance) = 24 inches
