How to Read Slope Gradient and Incline Measurements
Before you can calculate how steep of a slope your car can handle, you need to understand how slope measurements work. Slope gradient is typically expressed as a percentage or an angle of inclination. A slope percentage tells you the amount of vertical rise for every 100 feet of horizontal distance, while the angle of inclination is measured in degrees.
When it comes to driving, the slope percentage is more useful as it directly correlates to the strain on your car’s engine and transmission. A slope of 10% means that for every 100 feet you travel horizontally, you’ll rise 10 feet vertically. To determine the slope percentage, you can use a slope gradient calculator or measure it yourself using a clinometer or inclinometer app on your smartphone.
Another way to express slope gradient is in terms of degrees. A slope of 45 degrees is equivalent to a 100% slope gradient, which means you’re climbing a vertical wall. A 30-degree slope is equivalent to a 58% slope gradient, which is challenging for most cars. It’s essential to understand these measurements to determine whether a slope is safe to drive on.
When you’re measuring slope gradient or incline, remember that accuracy matters. Even a slight variation in the measurement can significantly impact your car’s performance. It’s crucial to take multiple measurements and get an average reading for the slope you’re planning to drive on.
