How to convert percentage to GPA
The standard "linear" method divides your percentage by 100 and multiplies by the maximum of your target GPA scale. For a U.S. 4.0 scale:
So 80% becomes (80 ÷ 100) × 4.0 = 3.2 GPA. This is a back-of-the-envelope conversion — most universities actually use grade-range tables (e.g. 80–89% = A = 4.0, not a sliding scale). For an exact figure on your transcript, you need your school's grading scheme. Pick your university to see its official table.
How to convert GPA to percentage
Invert the linear formula:
A 3.5 GPA on a 4.0 scale is (3.5 ÷ 4.0) × 100 = 87.5%. As with the other direction, this is an approximation — your university's scheme assigns a percentage range to each grade, so any value within the range maps to the same GPA.
Indian / Pakistani CGPA → US 4.0 GPA: the official formulas
The most common linear conversion from a 10-point CGPA to a 4.0 GPA is:
For Indian students applying to U.S. universities, this is what online converters and most admissions chance calculators use. The two important caveats:
- WES does not use this formula. WES (World Education Services) evaluates each course against the country's standard scale and assigns a U.S. letter grade, then computes the GPA from those letters. If your program requires WES, the linear number you compute here will not match the WES result.
- Indian universities don't all use the same 10-point scale. A 7.0 CGPA from one university might mean "first division, ≥ 60%" while another might require ≥ 65% for the same grade point. Check your university's grade-card legend.
Why different universities give different conversions
A university's grading scheme is a policy, not a math identity. Two universities looking at the same percentage transcript can assign different GPAs because:
- Their cutoffs differ (one school's A starts at 85%, another's at 90%).
- Their scales differ (4.0 vs 4.3 vs 5.0 vs 10-point).
- They include or exclude plus/minus modifiers.
- They count failed courses differently (retakes replaced, averaged, or both retained).
The linear conversion ignores all of this. It works as a rough sanity check; it doesn't work as the official number on an application.
When admissions offices reject these calculators (WES, ECE, official evaluations)
Most U.S. graduate programs require a credential evaluation when your transcript isn't from a U.S. institution. Common evaluators:
- WES (World Education Services) — most widely accepted.
- ECE (Educational Credential Evaluators) — accepted by many programs as an alternative.
- SpanTran, IEE, others — accepted by specific schools.
These evaluators do a course-by-course translation, not a single-formula conversion. If your target program lists "WES required" or "course-by-course evaluation," using the linear value from this page on the application is the wrong answer. Use this calculator to know roughly where you stand for shortlisting; use the evaluator for the form.
