Under the JNTUH R22 regulations, a CGPA of 7.5 is exactly 70% of marks.
The working
Clause 11.2: % of Marks = (final CGPA − 0.5) × 10
- 7.5 − 0.5 = 7.0
- 7.0 × 10 = 70%
Why this particular value matters more than the ones around it
70% is one of the most frequently used eligibility lines on Indian application forms — for jobs, for higher studies, and for a good number of scholarship schemes. A CGPA of 7.5 lands exactly on it, with nothing to spare.
That makes 7.5 a value worth being precise about. At 7.4 you are at 69% and below the line; at 7.6 you are at 71% and clear of it. The gap between passing and failing an automated eligibility filter is one decimal place of CGPA — which is a fairer reason to care about a 0.1 than most of the reasons students give themselves.
If you are sitting just under it, the target CGPA calculator will tell you what you need from your remaining credits to cross it, and whether crossing it is still arithmetically possible.

- 7.6 → 71%
- 7.7 → 72%
Every value from 4.0 to 10.0 is on the conversion table.
Rounding, and why you should not
Because 7.5 converts to a clean 70, it is tempting to round the other way when you are close — to write 70% at 7.45, or to describe 7.48 as “roughly 7.5”. Do not. The percentage that matters is the one your university prints, and it will be calculated from your actual CGPA to two decimal places, not from a rounded one. A resume that claims a number the marks memo does not support is a problem you meet later, at verification, when it is much harder to explain.
