How University of Madras converts CGPA to percentage

Enter your CGPA above to convert it instantly.

Worked example

Take a CGPA of 7.5 on the 10-point scale. Applying the official University of Madras formula % = CGPA × 10 (derived from the University's marks ÷ 10 grade-point table — not a stated conversion rule) gives a percentage of about 75%. Change the CGPA in the calculator above and the percentage updates instantly using this same formula.

Why the formula matters

Using the official conversion keeps your percentage defensible if an admissions office or employer asks how you calculated it.

Source & verification

University of Madras — Handbook on Integrated Common Regulations for the UG and PG Degree Programmes offered in the Affiliated Arts and Science Colleges under CBCS-2019 (UG Reg. 8–9; PG Reg. 7–8): marks→grade-point table 90–100 → 9.0–10.0 (O), 80–89 → 8.0–8.9 (D+), 75–79 → 7.5–7.9 (D), 70–74 → 7.0–7.4 (A+), 60–69 → 6.0–6.9 (A), 50–59 → 5.0–5.9 (B), 40–49 → 4.0–4.9 (C), 00–39 → 0.0 (U); CGPA = ΣΣCniGni ÷ ΣΣCni.

NO EXPLICIT CONVERSION RULE: the University's regulations never say 'percentage = CGPA × 10'. They map marks to grade points in bands whose ranges run parallel to marks ÷ 10 (90–100 → 9.0–10.0, 80–89 → 8.0–8.9, … 50–59 → 5.0–5.9), and class cut-offs line up the same way (CGPA 6.0 ↔ 60% First Class, 7.5 ↔ 75% Distinction). CGPA × 10 therefore gives the credit-weighted average percentage. STATUS 'verified' (DERIVED): the formula is derived from the University's own published grade-point table, not quoted from a conversion rule — show 'Derived from the official grade-point table' on the page with a 'confirm against your mark statement' disclaimer. Classification: CGPA 9.0–10.0 First Class – Exemplary; 7.5–<9.0 First Class with Distinction; 6.0–<7.5 First Class; 5.0–<6.0 Second Class (UG Reg. 8 also states First Class = 60% aggregate, Second = 50–<60%). PG uses the same table with 00–49 = U. The regulations cover affiliated (non-autonomous) Arts & Science colleges; autonomous colleges may modify them. MCA and the older university-department CBCS (2007-08) report Weighted Average Marks (WAM) / Overall Weighted Percentage of Marks (OWPM), i.e. a direct percentage on the mark statement — use that where printed.
