CGPA to GPA Calculator

Divide your CGPA by the maximum of your grading system, then multiply by 4. On a 10-point scale that is GPA = CGPA / 10 × 4, so a CGPA of 8.0 becomes a 3.2. On a 5-point scale it is GPA = CGPA / 5 × 4. This proportional method is the one behind the common 10 point to 4 point conversion.

A 10-point CGPA of 8.0 converts to a 3.2 on the US 4.0 scale, because 8.0 / 10 × 4 = 3.2. That maps to roughly a B+ letter grade and an 80% equivalent. For reference, a 9.0 CGPA becomes 3.6 and a perfect 10 becomes 4.0.

Use the same proportional method with 5 as the maximum: GPA = CGPA / 5 × 4. A 5-point CGPA of 4.0 becomes 3.2, and a 4.5 becomes 3.6. Select the 5-point scale in the calculator and it applies this automatically.

Not exactly. This calculator uses the simple proportional formula (CGPA divided by the scale maximum, times 4), which many US application portals accept when you self-report. Agencies like WES use their own grade-band tables, and CBSE in India often estimates percentage as CGPA × 9.5. Check your target school's policy, since some require an official credential evaluation.

The calculator maps the 4.0 GPA to standard US letter bands: 4.0 is an A, 3.7 an A-, 3.3 a B+, 3.0 a B, and so on down to F. It uses midpoint cutoffs, so a 3.2 GPA shows as a B+. Letter grades are an approximation, since each school sets its own thresholds.

The arithmetic is exact, but the meaning is an estimate. A proportional conversion treats every scale as linear, which can understate a strong CGPA compared with grade-band methods. Use the result as a quick reference and rely on an official transcript evaluation for admissions or transfer credit.
