US Grading System and GPA Scale
The US grading system often uses letter grades, percentages, and GPA points to summarize course performance. This page explains common 4.0 GPA planning patterns without replacing your school's transcript rules.
- Common range
- Commonly 0.0 to 4.0 for unweighted GPA, with some schools using plus/minus points or weighted scales above 4.0.

How this system is used
- Used by many US high schools and colleges to summarize graded coursework with letter grades, percentages, GPA points, or transcript-specific rules.
- Often combines grade points and credits, so higher-credit courses have more effect.
- May appear as semester GPA, cumulative GPA, weighted GPA, or unweighted GPA.
Common interpretation
- A 4.0 commonly represents A-level performance on an unweighted scale.
- Values near 3.0 commonly reflect B-level performance on many 4.0 scales.
- Weighted high school scales can exceed 4.0 when advanced courses receive bonus points.
Conversion cautions
- Do not treat one 4.0 mapping as universal. Schools may handle A+, A-, pass/fail, repeats, and withdrawals differently.
- International transcript conversion is usually handled by the receiving school or a credential evaluation service.
- Use GPA calculators for planning estimates, not as official transcript conversion.
Limits of this reference
- No single US-wide GPA policy controls every school.
- Admissions offices may recalculate GPA using their own method.
- Weighted GPA rules vary widely by high school district and transcript policy.

- No. The 4.0 scale is common, but some schools use weighted scales, 4.3 scales, percentage grades, or custom transcript rules.
- Can GradeTally convert any international grade to a US GPA?
- No. GradeTally can help with planning math, but official conversion depends on the school, evaluator, or admissions office.
- Is weighted GPA standardized across the US?
- No. Weighted GPA may appear on a specific high school transcript, but the weighting method is school-specific.
