Algebric Difference in Grade formula

\(\large{ A =  g_2 \;-\; g_1 }\)   

Where:

 Units English Metric
\(\large{ A }\) = algebric difference in grade (%) \(\large{dimensionless}\)
\(\large{ g_1 }\) = tangent grade of a slope given in % \(\large{dimensionless}\)
\(\large{ g_2 }\) = tangent grade of a slope given in % \(\large{dimensionless}\)
