A student guide to 4.0, 4.3, 5.0, percentage, and letter grade scales without claiming official conversion.
Written and maintained by StudyCalc AI Content checked August 6, 2026
Schools may use a 4.0 GPA scale, 4.3 scale, 5.0 weighted scale, percentage grades, letter grades, pass/fail rules, or local credit systems.
A letter such as A or B can map to different grade points depending on the country, institution, course level, and transcript policy.
Many US schools use 4.0, 4.3, or weighted 5.0-style scales, while Korean universities may use 4.3, 4.5, percentage, or letter-grade systems depending on the institution.
The same letter grade can mean different grade points across schools. Treat any GPA estimate as a planning reference unless your school publishes the exact conversion rule.
A percentage score is often continuous, while a letter grade usually groups ranges into A, B, C, D, or pass/fail outcomes.
When a syllabus lists category weights in percentages but the transcript shows letters or grade points, calculate the course estimate first and then compare it with the official scale.
Attendance rules can be based on total classes, seat time, labs, excused absences, tardies, or a minimum percentage such as 75%, 80%, or 90%.
Use attendance calculators to understand the direction of risk, then verify the exact absence policy in the syllabus or student handbook.
Enter the scale and weights from your own syllabus instead of copying a generic country table. Recalculate after any new grade, absence, deadline, or policy update.
For official transcripts, scholarships, admissions, graduation, or visa-related decisions, use the method required by the school or organization receiving the record.
Use the GPA calculator as a planning tool by entering the scale your school actually uses. Do not treat a generic scale as an official transcript conversion.
When applying for graduation, scholarships, exchange programs, or admissions, use the official conversion method required by that organization.
The GPA Calculator helps combine courses, credits, and grade points. The Target GPA Calculator estimates the term GPA needed to reach a cumulative goal.
For course-level planning, use the Weighted Grade Calculator or Final Grade Calculator before updating GPA expectations.

Example 1: equal-credit grades A+, A0, and B+ average about 3.87 on the cited SNU 4.3 values but 4.00 on the cited UST 4.5 values. The labels look similar while the points differ.
Example 2: the Oxford document service and ECTS overview describe academic documents and credits, not a numerical GPA mapping. StudyCalc AI therefore does not invent a conversion from either source.
