How to Get a CGPA to Percentage Conversion Certificate (Not Every University Issues One)
By Ritusmoi Kaushik · Published: 20 July 2026 · 9 min read
A friend's younger brother hit this last August. Final-year student, VTU, applying to a PSU that wanted "percentage marks as certified by the University". He walked into the examination section with his grade card, asked for a CGPA-to-percentage conversion certificate, and was told the university doesn't issue that document. Not "come back Monday". Just: we don't make that.
He assumed he'd been fobbed off by the wrong clerk. He hadn't. VTU genuinely doesn't issue one, and he'd lost a week finding that out.
That's the thing nobody tells you before you start queueing. Whether this certificate exists depends entirely on which university you went to, and the answer ranges from "yes, here's the form and the fee" to "there is nothing to issue, it's already printed on your grade card". So it's worth knowing which situation you're in before you spend a week in the wrong queue.
Two different documents get called the same thing
When a form says "conversion certificate", it's usually asking for one of two things, and people conflate them constantly.
The official one. Issued by your university's examination section, on their format, signed and stamped. It states your CGPA, the percentage, and the formula they applied. It takes days to weeks, usually costs a fee, and it's the only version that carries the university's authority.
The self-generated one. A clean document you produce yourself that states your CGPA, the equivalent percentage, the exact formula your university publishes, and where that formula comes from. No stamp. What it gives you is a defensible number with the working shown, which is what most placement forms and HR portals actually want when they ask you to justify a percentage.
Which one you need is a question about the form, not about you. A PSU application that says "as certified by the University" means the stamped one. A campus placement portal that just wants a percentage in a box, with something to back it up if challenged, does not.
Which universities actually issue one
Here's where it lands for the universities we've checked the process on. This is the table I wish that VTU student had seen before he took a bus to the examination section.
| University | Dedicated certificate? | What to do |
|---|---|---|
| Anna University | Yes | Prescribed form from the Controller of Examinations site, or apply via the online services portal, with your consolidated grade sheet, photo ID and the fee. Allow a few weeks. |
| SPPU | Yes | Apply to the SPPU examination section with your original grade sheet. |
| JNTUH | Yes | Request from the JNTUH Examination Branch, or your affiliated college's exam section, on the university format. |
| MAKAUT | Via transcript | Apply through the MAKAUT Member's Area for a transcript or duplicate grade card, or ask your college's Controller of Examinations. |
| RGPV | No, and you don't need one | The formula is CGPA × 10, so your percentage is already what the grade card implies. The document that carries it is the transcript: submit the Transcript Form to the Registrar's office in Bhopal. |
| VTU | No | VTU doesn't issue one. Compute it with VTU's official formula and have your college principal certify it on college letterhead, citing VTU's CGPA formula notification. |
| Mumbai University | On request only, new method | Formula-based conversion was repealed on 1 January 2026. Percentage is now computed from actual marks and the certificate is issued only if you ask. See below. |
If your university isn't on that list, don't assume either way. Ring your examination section and ask the question in exactly these words: "do you issue a CGPA to percentage conversion certificate, and what's the form and fee?" Five minutes on the phone beats a wasted trip, and the answer varies even between universities in the same state.
Mumbai is its own situation now
If you're from Mumbai University, the ground moved under this question. On 1 January 2026, via Circular No. Exam/Result/803 of 2026, Mumbai repealed formula-based conversion outright. The old (CGPA × 7.1) + 11 for general degrees, and (CGPA × 7.4) + 12 for engineering above CGPA 7, no longer govern new conversions.
What replaced it: your college computes the percentage from your actual marks across Sem-I to Sem-VI, and the university issues a conversion certificate only on request. It's opt-in now. Nobody hands it to you automatically.
Which matters because a good chunk of the internet hasn't caught up. Calculator sites still hand Mumbai students a number off 7.1 + 11, and for a 2026 graduate that number isn't just outdated, it's not the university's method any more. I wrote the whole thing up in the Circular 803 post, including a worked example where a topper's percentage swings from 79.16% under the old formula to 93.17% under the new marks-based one. That is not a rounding difference.
If your university doesn't issue one
This is the common case and it's genuinely fine. The accepted route, and the one VTU itself points to, is a letter on college letterhead:
- State your name, roll or enrolment number, programme and CGPA.
- State the university's official conversion formula, word for word.
- Show the arithmetic. "CGPA 8.42 × 10 = 84.20%" is enough.
- Cite where the formula comes from: the notification, circular or regulation.
- Get it signed by the principal or HoD, with the college stamp.
The citation is what makes it hold up. A percentage with no stated source is one person's opinion. A percentage with the university's own formula printed next to it is a claim anyone can check in a minute, which is exactly what a recruiter who's been lied to before wants to see.
The trap: converting with the wrong formula
Before you certify anything, make sure the number is right, because this is where certificates go wrong in a way that's hard to walk back. There is no single national formula. The generic × 9.5 that half the internet applies to everything is CBSE's school-level rule, and it is not your university's rule unless your university says so.
| Formula | Universities | 8.0 CGPA gives |
|---|---|---|
| CGPA × 10 | Anna, RGPV, Calcutta, VTU (2021/22 schemes), SRM, VIT, Amity | 80.00% |
| CGPA × 9.5 | DU (CBCS batches), CBSE | 76.00% |
| (CGPA − 0.75) × 10 | AKTU, SPPU, MAKAUT, VTU (2015/17/18 schemes) | 72.50% |
| (CGPA − 0.5) × 10 | JNTUH, GTU | 75.00% |
Same 8.0 CGPA, four legitimate answers between 72.50% and 80%. Nearly eight marks of spread, decided entirely by which university's rule applies. Put the wrong one on a certified document and you've certified a wrong number, under a signature, on a form that gets cross-checked against your transcript later.
Two more things worth knowing before you write a class on anything. If a scheme or regulation applies to your batch specifically, use that one. VTU's older schemes subtract 0.75 while the current ones don't, and DU's CBCS and NEP batches convert differently. And if you were planning to write "First Class" next to the percentage, check that your university actually awards one. MAKAUT and Calcutta award no class at all, and DU has no Distinction tier, whatever the calculator sites print.
When the stamped one is worth the wait
Get the official, stamped certificate when the form explicitly says certified by the university, when it's a PSU or government recruitment, or when a credential evaluator like WES or a foreign university admissions office asks for an institutional conversion. Those readers want the institution's word, not yours, and no self-made document substitutes for it. Start early: a few weeks is normal, and application deadlines don't care.
For everything else (campus and off-campus placement portals, HR forms that want a percentage with something behind it, internship applications), a clean document stating the number, the formula and the source does the job. That's the gap the conversion certificate generator fills: it applies your university's actual formula rather than a generic one, prints the source, and you can pull a free watermarked copy to check every detail before deciding it's what you need. It is not a university-issued certificate and it doesn't pretend to be.
Here's my take, marked as a take: most students chasing a stamped certificate don't need one and are burning a week of a placement season on it. The form usually wants a number it can trust, not a seal. Read what the form literally asks for before you join the queue. And if it does say "certified by the University", stop reading listicles and go start that application today, because the queue is the bottleneck, not the paperwork.
Sources and notes
The per-university processes above come from each university's own examination-section route as recorded on their sites, and the formulas from the official notifications, circulars and regulations tracked in GradeKar's source registry: VTU's CGPA formula notification, SPPU's Circular 332/2020, JNTUH's B.Tech academic regulations, MAKAUT's percentage notice, and Mumbai's Circular Exam/Result/803 of 2026 for the repeal.
Fees, forms and turnaround times change without much announcement, and a few universities have moved these services onto student portals recently. Treat the "what to do" column as the starting point and confirm the current process with your own examination section before you pay anything. If your university's formula on our site ever looks wrong against a document you're holding, tell us and we'll fix it.
