How to Calculate the Lawn Slope

    There are two common ways to measure the slope of a surface: degrees and percentage.


    The simplest way is to measure the slope in percentage using the formula given in Figure 1, where:
    L – is the length of the slope
    H – is the height difference


    After calculating the slope in percentage, use the table below to convert it into degrees
