1. What is a Grade Calculator by Percentage?

Definition: This calculator converts a percentage score to a grade point based on a specified grading scale.

Purpose: It helps students and educators translate percentage scores to different grading systems (e.g., 4.0 scale, 10.0 scale).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Grade \) — Calculated grade point
• \( Percentage \) — Percentage score (0-100)
• \( Scale \) — Maximum grade point scale (e.g., 4.0, 10.0)

Explanation: The percentage is converted to a decimal (divided by 100) then multiplied by the grading scale maximum.

3. Importance of Grade Conversion

Details: Different institutions use different grading systems. This conversion helps standardize grades for comparison or transfer purposes.

4. Using the Calculator

Tips: Enter your percentage score (0-100) and the grading scale maximum (e.g., 4.0 for standard GPA scale). All values must be valid (percentage between 0-100, scale > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's the most common grading scale?
A: In the US, 4.0 is standard for GPA. Other countries might use 10.0, 20.0, or percentage scales directly.

Q2: Does this work for weighted grades?
A: No, this is a basic conversion. Weighted grades require additional factors for honors/AP classes.

Q3: How accurate is this conversion?
A: It provides a linear conversion. Some schools may use non-linear scales (e.g., 90-100 = A = 4.0).

Q4: Can I convert back from grade points to percentage?
A: Yes, by rearranging the formula: Percentage = (Grade/Scale) × 100.

Q5: What if my school uses letter grades?
A: You'll need to know your school's percentage ranges for each letter grade first.
