Understanding the Formulas

There are a couple of formulas you might find useful, depending on what you're trying to achieve. The most common scenario is converting degrees to a percentage of slope. The formula for this conversion is:

Percentage of Slope = [ Tan ( Degrees ) ] x 100

For example, an angle of 45 degrees would translate to a 100% slope. This means for every unit of "run" (horizontal distance), there's an equal unit of "rise" (vertical distance).

For converting degrees to a percentage of a circle, you can use this formula:

Percentage = (Degrees / 360) * 100

So, 90 degrees would represent 25% of the circle.

When is This Useful?

  • Construction and Engineering: Determining roof pitch, grading land, or calculating the incline of a road.
  • Data Visualization: Creating pie charts where each slice represents a percentage of the whole.
  • General Math: Understanding proportions and relationships between angles and their corresponding percentages.
