Convert CGPA to percentage, percentage to CGPA, US GPA to percentage, and compute semester GPA from credits and grades. Built for Indian (CBSE, VTU, Anna) and US 4.0 grading systems.
Students often need different conversions for college applications, transcript translation, scholarships, and study-abroad evaluations. This page covers Indian and US grading conventions in one place.
CBSE uses 9.5 as the default multiplier. Engineering universities like VTU often subtract 7.5 from CGPA and multiply by 10. Always confirm your institution's official conversion formula.
Each board uses its own CGPA-to-percentage formula — visit the page for your specific institution.

Solve percentage of, percentage change, and reverse percentage calculations.
Find your exact age in years, months, and days for school admissions.
Calculate exam-date differences and academic deadlines.
Plan education savings with monthly SIP projections.
Different boards and universities use different grading systems. CBSE and most Indian schools use a 10-point CGPA scale, where percentage is approximately CGPA × 9.5. US universities use a 4.0 GPA scale where letter grades map to grade points and percentages are derived as (GPA / 4) × 100.
Engineering universities such as VTU, Anna University, and JNTU may use formulas like (CGPA − 0.75) × 10 or (CGPA − 0.5) × 10, so always confirm the official conversion document of your institution before submitting any official form.
This calculator covers all four major directions — CGPA to percentage, percentage to CGPA, GPA to percentage, and percentage to GPA — plus a credit-weighted subject-wise mode for computing CGPA or GPA from your marksheet directly.
Pick your grading region first — India for 10-point CGPA or USA for the 4.0 scale. Then choose a mode based on what you have and what you need: convert from CGPA, convert from percentage, or compute fresh from subject credits and grades.
For the subject-wise mode, enter each subject with its credit hours and the grade you received. The calculator returns a credit-weighted CGPA or GPA along with the equivalent percentage and class or honors band.
Students applying abroad usually need both CGPA and percentage representations of the same transcript. This page lets you compute and verify both in seconds without manual arithmetic.
On the Indian 10-point scale, an O (Outstanding) is typically 90% and above, A+ is 80 to 89%, A is 70 to 79%, B+ is 60 to 69%, and B is 55 to 59%. The pass mark is usually 35 to 40% depending on the board.
On the US 4.0 scale, an A is 4.0 (90 to 100%), a B is 3.0 (80 to 89%), a C is 2.0 (70 to 79%), and a D is 1.0 (60 to 69%). Honors thresholds typically begin at 3.5 GPA, and Summa Cum Laude usually requires 3.9 or higher.
These ranges are approximate. Many universities use weighted GPAs that allow grades above 4.0 for honors and AP courses, which this calculator does not include since the unweighted scale is the standard reference internationally.
