The percentage to letter grade conversion is a standardized method of translating numerical scores into letter grades (A, B, C, D, F) that are commonly used in academic institutions.

2. How Does the Calculator Work?

The calculator uses the standard conversion formula:

Where:

• \( L \) — Letter grade (A, B, C, D, F)
• \( P \) — Percentage score (0-100)
• \( f \) — Conversion function

Conversion Scale:

• 90-100% = A
• 80-89% = B
• 70-79% = C
• 60-69% = D
• Below 60% = F
