What is a 58 percent grade?

A 58 percent grade is considered a steep grade in terms of slope measurement. It means that the rise of the slope is 58 units for every 100 units of horizontal distance. In practical terms, a 58 percent grade is equivalent to a slope of approximately 30 degrees. This steepness makes it difficult to walk or drive on, and special precautions or construction techniques may be required to navigate or build on such a slope.
