Understanding the 4.0 GPA Scale
The 4.0 GPA scale is the most widely recognized academic grading system in the United States. Used extensively by high schools, universities, and graduate schools, it acts as a standardized currency for comparing student achievements.
Under this system, the letter grades you earn in class are assigned standard point values ranging from 4.0 down to 0.0. By translating your scores to standard numbers, the 4.0 scale allows schools to calculate a running average of your coursework across all semesters.
How to Calculate GPA on a 4.0 Scale
Here is how traditional percentage scores align with the standard 4.0 GPA scale:
- 93% – 100%: A (4.0 GPA)
- 90% – 92%: A- (3.7 GPA)
- 87% – 89%: B+ (3.3 GPA)
- 83% – 86%: B (3.0 GPA)
- 80% – 82%: B- (2.7 GPA)
- 77% – 79%: C+ (2.3 GPA)
- 73% – 76%: C (2.0 GPA)
- 70% – 72%: C- (1.7 GPA)
- 65% – 69%: D (1.0 GPA)
- Below 65%: F (0.0 GPA)
Why is a 4.0 scale important?
Admissions committees use the 4.0 scale as a baseline to evaluate candidates fairly. Because a 90% score might equal an 'A' grade at one school but a 'B' at another, converting grades to the standard scale eliminates local discrepancies.
