Calculate Ramp Grade



Formula

To calculate the ramp grade:

\[ \text{Grade} (\%) = \left( \frac{\text{Rise}}{\text{Run}} \right) \times 100 \]

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.

Example Calculation 1

Let's assume the following values:

Using the formula:

Step 1: Divide the rise by the run and multiply by 100:

\[ \text{Grade} = \left( \frac{6}{72} \right) \times 100 = 8.33\% \]

The ramp grade is 8.33%.

Example Calculation 2

Let's assume the following values:

Using the formula:

Step 1: Divide the rise by the run and multiply by 100:

\[ \text{Grade} = \left( \frac{12}{144} \right) \times 100 = 8.33\% \]

The ramp grade is 8.33%.
