Enter the rise and run of a ramp into the calculator to determine the grade of the ramp. The grade is calculated as a percentage, which indicates the incline level of the ramp.
Ramp Grade Formula
The following formula is used to calculate the ramp grade.
Grade (%) = (Rise / Run) * 100
Variables:
- Rise is the vertical height of the ramp (inches)
- Run is the horizontal length of the ramp (inches)
- Grade is the slope of the ramp expressed as a percentage (%)
To calculate the ramp grade, divide the rise by the run and then multiply by 100 to get the percentage.
What is a Ramp Grade?
A ramp grade is a measure of the steepness or incline of a ramp. It is expressed as a percentage that represents the ratio of the vertical rise to the horizontal run. This measurement is important for ensuring that ramps are built to standards that make them safe and accessible, especially for wheelchair users and others with mobility challenges.
How to Calculate Ramp Grade?
The following steps outline how to calculate the Ramp Grade.
- First, measure the vertical rise of the ramp (Rise) in inches.
- Next, measure the horizontal length of the ramp (Run) in inches.
- Use the formula from above to calculate the Grade (%) = (Rise / Run) * 100.
- Finally, calculate the Ramp Grade (Grade) as a percentage.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Rise of the ramp (Rise) = 12 inches
Horizontal length of the ramp (Run) = 120 inches
