Grade Conversion Basics
Grade conversion involves translating percentage scores into letter grades or vice versa. This process is commonly used in education systems worldwide. The exact ranges for each letter grade can vary depending on the institution and country.
Common Conversion Formula
Letter Grade = CASE WHEN Percentage ≥ 90 THEN 'A'
WHEN Percentage ≥ 80 THEN 'B'
WHEN Percentage ≥ 70 THEN 'C'
WHEN Percentage ≥ 60 THEN 'D'
ELSE 'F'
This is a simplified version of the conversion process. Many institutions use more granular scales or have different cutoffs for each letter grade.
Common Grading Systems
Different countries and institutions use different grading systems. Here are some common examples:
US Grading System
| Percentage Range | Letter Grade | Description |
|---|---|---|
| 90-100% | A | Excellent |
| 80-89% | B | Good |
| 70-79% | C | Satisfactory |
| 60-69% | D | Needs Improvement |
| Below 60% | F | Fail |
UK Grading System
| Percentage Range | Grade | Description |
|---|---|---|
| 70-100% | A | Distinction |
| 60-69% | B | Merit |
| 50-59% | C | Pass |
| Below 50% | F | Fail |
The calculator uses the US grading system by default, but you can select the UK system or other options if available.
Worked Examples
Example 1: US Grading System
If a student scores 85% in a course using the US grading system:
- 85% falls in the 80-89% range
- According to the US system, this corresponds to a B grade
- The student receives a B for their performance
Example 2: UK Grading System
If a student scores 65% in a course using the UK grading system:
- 65% falls in the 60-69% range
- According to the UK system, this corresponds to a B grade
- The student receives a B for their performance
These examples demonstrate how the same percentage can translate to different letter grades depending on the grading system used.
