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

## 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 % $$\large{dimensionless}$$
