Under the JNTUH R22 regulations, 67% of marks is a CGPA of 7.2.
The working
Clause 11.2 states the conversion one way round — % of Marks = (final CGPA − 0.5) × 10. Going from a percentage back to a CGPA is the same rule rearranged:
CGPA = (percentage ÷ 10) + 0.5
- 67 ÷ 10 = 6.7
- 6.7 + 0.5 = 7.2
Why people search this direction
Forward conversion — CGPA to percentage — is what you do for an application form. The reverse is what you do when someone hands you a percentage and you need to know what it means on the scale you actually think in.
That happens more often than you would expect. A job posting states a 67% cut-off and you hold a CGPA. An older sibling’s marks memo shows a percentage from a different regulation. A scholarship form asks for one and your college certificate gives the other.
The mistake in this direction is to divide by 9.5, or to move the decimal point and stop — reading 67% as a 6.7 CGPA. That drops the 0.5 and understates the CGPA by half a point, which is a wide margin on a ten-point scale.

| Grade | Grade points | Marks range |
|---|---|---|
| O | 10 | 90% and above |
| A+ | 9 | 80% to below 90% |
| A | 8 | 70% to below 80% |
| B+ | 7 | 60% to below 70% |
| B | 6 | 50% to below 60% |
| C | 5 | 40% to below 50% |
| F | 0 | Below 40% (Fail) |
| Ab | 0 | Absent |
Values around 67%
- 65% → 7.0
- 66% → 7.1
- 67% → 7.2
- 68% → 7.3
- 70% → 7.5
Because the rule is linear, every whole percentage point is worth exactly 0.1 of CGPA. The full conversion table runs the other direction for every value from 4.0 to 10.0.
One caution on reverse conversion
Converting forwards gives you a figure your university would recognise. Converting backwards gives you an equivalent — useful for comparison, but not something to write on a form as though the university had issued it. If a form asks for CGPA, give the CGPA on your marks memo, not one you derived from a percentage.
