Curve Method
ℹ️ The Square Root Curve multiplies √(raw score) by 10. A 64 becomes an 80, a 81 becomes a 90. Lower scores benefit more — great for tough exams.

📐 Curve Formula
Curved Score = √(Raw Score) × 10
Example: √64 × 10 = 8 × 10 = 80  ·  √81 × 10 = 9 × 10 = 90

Square Root Curve Calculator

The Square Root Curve Calculator is a simple and accurate online tool that helps you convert percentage grades into square root curve grades instantly. It is designed to make grade evaluation fair, easy, and transparent for students and teachers. Just enter your percentage score, and the calculator will automatically apply the square root formula to give you the curved grade within seconds.

Square Root Curve Formula

The calculator uses a simple mathematical formula:

SRG = √G × 10

SRG = Square Root Curve Grade

G = Original Percentage Grade

√G = Square root of the percentage grade

After calculating the square root, the result is multiplied by 10 to convert it into a curved percentage score.

Example

Original Grade: 10%

Step 1: √10 ≈ 3.162

Step 2: 3.162 × 10 = 31.62%

So, a 10% score becomes approximately 31.62% after applying the square root curve.

How to Use the Square Root Curve Calculator

Using the tool is hassle-free. Let’s discuss how to use it.

Step 1: Enter your percentage grade in the input box
Step 2: Click on the Calculate button
Step 3: Instantly view your square root curve grade result
