CGPA to percentage:
convert your grade point average

How to convert CGPA to percentage

To convert CGPA to percentage, multiply the CGPA by the conversion factor that your university or board publishes. For many 10-point systems that factor is 9.5, so the percentage is CGPA × 9.5.

There is no single national rule. A CGPA is a number on the institution's own grading scale, and each institution decides how that number maps to marks. The method below is the most commonly used one, but always confirm it against your own documents.

1. 1Find your final CGPA on the grade card or transcript.
2. 2Find the conversion rule printed by your institution (a factor, a formula or a table).
3. 3Multiply the CGPA by the factor, or apply the formula.
4. 4Write the result with two decimal places and the symbol %.

Worked example: 8.4 CGPA

A student finishes a four-year programme with a CGPA of 8.4 on a 10-point scale. Their institution states that percentage equals CGPA times 9.5.

Now compare a university that publishes an offset formula instead, for instance (CGPA − 0.75) × 10. The same 8.4 gives (8.4 − 0.75) × 10 = 76.5%. A gap of 3.3 points from the same grade point average shows why the rule must come from the institution, not from a website.

CGPA to percentage chart (6.0 to 10)

For values between rows, remember that under the 9.5 rule every 0.1 of CGPA adds 0.95 percentage points. A CGPA of 8.4 is the 8.0 row (76.00%) plus 4 × 0.95 = 3.80, which gives 79.80%.

Read the second column if your institution uses the 9.5 multiplier and the third only if it explicitly publishes the offset rule. The table is a comparison, not a recommendation.

Notice that even the top CGPA of 10.0 does not become 100% under either rule. That is built into the formulas, so a form that asks for a percentage often states which conversion it will accept.

Where the CGPA itself comes from

CGPA is a credit-weighted average of every course you have completed. Semesters with more credits count for more, which is why you should not average the SGPAs of different semesters with a plain mean.

The difference of 0.02 looks tiny, but multiplied by 9.5 it moves the percentage by about 0.2. Where a form has a hard threshold, that can be the difference between qualifying and not. Use the CGPA printed on the final transcript whenever one exists.

When a percentage is asked for and which rule applies

Eligibility rules in job applications, entrance forms, scholarships and some government recruitments are often written in percentages, even when the degree is graded in CGPA. The recipient usually accepts the conversion given by the awarding institution.

Read the field label closely. Some portals ask for "percentage as per university conversion", some give a field for the CGPA and a separate one for the percentage, and some accept either. Entering a number that your own certificate cannot support invites trouble at document verification.

If a form demands a minimum of 60%, a CGPA of 6.32 clears it under the 9.5 rule (6.32 × 9.5 = 60.04), while 6.30 does not (59.85%). Small differences matter at thresholds, so work from the exact CGPA, not a rounded one.

So which rule do you use? The reliable source is always printed material from your own institution: the back of the grade card, the examination notification, or a conversion certificate from the registrar or controller of examinations. A rule found on a third-party site is only a guess until your institution confirms it.

If an employer or admission portal accepts a self-calculated percentage, quote the rule you used next to it, for example "76.00% (CGPA 8.0 × 9.5 as per university notification)". This shows the number is traceable.

The 9.5 factor belongs to 10-point CGPAs. A 4.0 scale needs its own table, and multiplying a 3.4 GPA by 9.5 would give 32.3%, which is plainly meaningless. For the US-style scale, see the guide to GPA.

Keep a copy of the notification with the date it was issued. Conversion rules are revised from time to time, so the rule in force when you graduated may be the one that applies to your certificate.

Rounding and cut-offs

Report two decimals unless the form tells you otherwise. A CGPA of 7.85 gives 7.85 × 9.5 = 74.575, which rounds to 74.58%.

That number sits just under a 75% cut-off that some forms use. Do not round it up to 75 on your own. Either quote 74.58% or ask whether the recipient accepts rounded values, because verification teams often recompute the conversion.

Rounding errors compound when you convert twice, for example from CGPA to percentage and then back to a CGPA for another form. Convert once from the original figure and keep the unrounded intermediate value.

Also keep full precision in the CGPA itself. If your transcript shows 7.85, use 7.85, not 7.9, since rounding the CGPA first changes the result to 75.05%.

Mistakes to avoid

• Using 9.5 for a university that publishes a different rule or table.
• Averaging semester SGPAs instead of using the final CGPA. Credits differ by semester, so a simple average is usually wrong.
• Multiplying a 4.0-scale GPA by a 10-point factor.
• Rounding the CGPA before converting and then rounding the percentage again.
• Treating a converted percentage as an official mark. The institution's transcript is the official record.

Applications abroad add one more layer. Many universities and credential services ask for an official transcript or their own evaluation, and a percentage you calculated yourself may be treated only as supporting information.

To go the other way, the guide to percentage to CGPA covers the reverse calculation and the rounding choices. The score percentage calculator on this page is useful for checking marks against totals.
