Enter the student’s percentage grade (%) into the Square Root Curve Grade Calculator. The calculator will evaluate the Square Root Curve Grade. 

Square Root Curve Grade Formula

The following two example problems outline the steps and information needed to calculate the Square Root Curve Grade.

SRG = SQRT(G) * 10

Variables:

  • SRG is the Square Root Curve Grade (%)
  • G is the student’s percentage grade (%) 

To calculate the square root curved grade, take the square root of the percentage grade, then multiply by 10.

How to Calculate Square Root Curve Grade?

The following steps outline how to calculate the Square Root Curve Grade.


  1. First, determine the student’s percentage grade (%). 
  2. Next, gather the formula from above = SRG = SQRT(G) * 10.
  3. Finally, calculate the Square Root Curve Grade.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

student’s percentage grade (%) = 80

SRG = SQRT(G) * 10 = ?
