What is the most commonly used term for slope grade in construction?

Grade percentage
Degree of slope
Elevation ratio
Slope angle

The correct answer is: Grade percentage

The most commonly used term for slope grade in construction is grade percentage. This term is widely utilized in civil engineering and construction to express the steepness of a slope in a way that is easily understood and communicated among professionals. Grade percentage is calculated by taking the rise (vertical change) divided by the run (horizontal distance) and multiplying by 100 to express it as a percentage. For instance, a slope that rises 10 feet over a horizontal distance of 100 feet would be referred to as a 10% grade. This percentage provides a straightforward way to convey how steep or gentle a slope is, which is crucial for grading and designing roadways, drainage systems, and various other projects. In contrast, other terms like degree of slope and slope angle may also describe the steepness of a slope but are less commonly used in construction contexts. Degree of slope refers to the angle measured in degrees rather than as a percentage, making it less practical for many applications, while elevation ratio is not a standard term commonly associated with slope measurement in construction.
