There is no single U.S. letter-to-point chart. If an authority calculates GPA, its current transcript legend or registrar policy owns the point values, included marks, and precision.
Three official examples
| Authority | A+ | A | A− | B+ | Important boundary |
|---|---|---|---|---|---|
| Notre Dame | Not listed | 4.000 | 3.667 | 3.333 | Publishes its own excluded and special marks |
| UC Davis | 4.000 | 4.000 | 3.700 | 3.300 | Has separate rules for P/NP, incomplete, and repeats |
| Georgia Tech | Not in the cited academic-average table | 4 | Not in that table | Not in that table | Publishes P/F and repeat treatment and truncates the average |
These tables are not interchangeable. Plus/minus notation does not make one policy inherently more accurate; it simply changes the values the named authority records.
Reproduce a table safely
- Identify the GPA owner and purpose.
- Save the effective catalog or policy version.
- Copy every supported grade symbol exactly.
- Record which marks enter numerator and denominator.
- Apply units and repeat rules from the same policy.
- Follow its rounding or truncation rule.
For a credit-weighted policy, calculate point value × included credits for each course, sum those quality points, and divide by included GPA credits.
Site limitation
This site's calculators use a fixed table—A+/A 4.0, A− 3.7, B+ 3.3 through D− 0.7, F 0.0—and optional fixed bonuses on some routes. They do not automatically use your institution's table. Use the result only as an estimate when the assumptions match.
Frequently asked questions
Does A+ always exceed A?
No. UC Davis assigns both 4.0, Notre Dame's cited table does not list A+, and another authority may differ.
Is 4.0 always unweighted?
Scale and weighting are separate policy fields. A maximum does not reveal course bonuses or inclusion rules.
Can I convert a percentage with this table?
Only when the authority publishes percentage bands. Do not attach generic percentage cutoffs to a letter table.
Bottom line
Treat letter-to-point conversion as an issuer-owned lookup, not a national standard.
