Algebric Difference in Grade

Algebric difference in grade, abbreviated as A, is the difference in grades.

 

Algebric Difference in Grade formula

\(\large{ A =  g_2 \;-\; g_1 }\)

Where:

\(\large{ A }\) = algebric difference in grade (%)

\(\large{ g_1 }\) = tangent grade of a slope given in %

\(\large{ g_2 }\) = tangent grade of a slope given in %
