Slope Gradient Formula:
| From: | To: |
Slope gradient is a measure of the steepness or incline of a surface, expressed as a percentage. It represents the vertical rise divided by the horizontal run, multiplied by 100 to convert to a percentage.
The calculator uses the slope gradient formula:
Where:
Explanation: The formula calculates the ratio of vertical change to horizontal distance and expresses it as a percentage for easy interpretation.
Details: Slope gradient calculations are essential in civil engineering, construction, road design, landscaping, and outdoor activities. They help determine the suitability of land for various purposes and ensure safety in construction projects.
Tips: Enter rise and run values in meters. Both values must be positive numbers greater than zero. The calculator will automatically compute the gradient percentage.
Q1: What is considered a steep slope?
A: Generally, slopes above 15% are considered steep, while slopes above 30% are very steep and may require special engineering considerations.
Q2: How is slope gradient different from slope angle?
A: Slope gradient is expressed as a percentage, while slope angle is expressed in degrees. They are related but different measurements of steepness.
Q3: What are typical gradient ranges for roads?
A: Main highways typically have gradients under 6%, while local roads may go up to 12%. Mountain roads can have gradients up to 25% in extreme cases.
Q4: Can I use different units for rise and run?
A: Yes, as long as both rise and run use the same units (feet, meters, etc.), the gradient percentage calculation remains accurate.
Q5: What does a 100% gradient mean?
A: A 100% gradient means the rise equals the run, creating a 45-degree angle. This represents a very steep slope.
