CGPA to Percentage Conversion Certificate Guide

What is a CGPA to percentage conversion certificate? Learn why recruiting companies (TCS, Wipro, Infosys, PSUs) and government bodies require it, sample certificate formats, and how to obtain one from your university registrar.

What is an Official Conversion Certificate?

Official Proof of Institutional Formula

An authoritative document issued by a university Controller of Examinations or Registrar certifying the exact mathematical algorithm used to convert a candidate's CGPA into percentage.

Why Do Employers and Universities Require It?

When you apply for competitive examinations (UPSC, State PSCs, GATE, CAT) or corporate recruitment drives (TCS, Infosys, Accenture, Public Sector Undertakings like ONGC, BHEL, and IOCL), company eligibility criteria specify minimum percentage cutoffs (e.g. 60% aggregate or equivalent CGPA).

Because different Indian universities follow wildly divergent formulas—ranging from CGPA × 10 to (CGPA - 0.75) × 10 and (CGPA × 7.1) + 11—employers require an official certificate to prevent candidates from self-calculating inflated percentages using non-applicable formulas.

How to Obtain a Conversion Certificate from Your University

  1. Check Your Marksheet First: In many universities (e.g. VTU, Anna University, Mumbai University), the conversion formula is already officially printed on the reverse side of your Consolidated Marks Card or Provisional Degree Certificate. Submitting a self-attested photocopy of the back side is universally accepted by HR verification teams.
  2. Download the Official University Circular: Visit your university's official website (e.g. vtu.ac.in or annauniv.edu) and download the official academic circular regarding CGPA to percentage conversion.
  3. Apply at the Registrar / Examination Branch: If an employer specifically demands a personalized certificate, submit a formal application to your university Controller of Examinations along with a nominal fee (typically ₹100–₹500) to receive an official sealed conversion letter.

TO WHOMSOEVER IT MAY CONCERN

This is to certify that Mr./Ms. [Student Name], bearing University Registration No. [Reg No], has completed the [Degree Name, e.g. B.Tech in Computer Science and Engineering] from this University during the academic period [2020–2024].

As per the official academic regulations of this University, the formula for converting Cumulative Grade Point Average (CGPA) into equivalent percentage of marks is:

Percentage of Marks = (CGPA - 0.75) × 10

Based on the above official formula, the candidate’s final cumulative score of 8.20 CGPA is equivalent to 74.50%.
