Converting R.G.M. College of Engineering & Technology (Autonomous), Nandyal percentage back to CGPA
R.G.M. College of Engineering & Technology (Autonomous), Nandyal (Andhra Pradesh) officially converts CGPA to percentage with % = (CGPA − 0.5) × 10. This page inverts that formula so you can estimate the CGPA behind a known percentage. Enter your percentage above and the calculator solves for the CGPA on the 10-point scale.
Worked example
The official R.G.M. College of Engineering & Technology (Autonomous), Nandyal formula is % = (CGPA − 0.5) × 10. Starting from a percentage of 75%, the formula reverses to a CGPA of about 8 on the 10-point scale. You can check this by running 8 through the forward R.G.M. College of Engineering & Technology (Autonomous), Nandyal CGPA to percentage calculator — it returns 75%, confirming the two directions agree.
Why this is an estimate, not an official figure
A college issues your percentage from your actual CGPA, not the other way around — so reversing the formula recovers the CGPA that would produce that percentage. When both numbers appear on your grade card, always quote the official CGPA rather than this estimate.
Source & verification
own — R.G.M. College of Engineering & Technology (Autonomous), Academic Regulations RGM-R-2020, §14.0: 'For any academic/employment purpose the following formulae shall be used for conversion of CGPA to % of marks. % of marks = (CGPA – 0.5) x 10.'
Applies to B.Tech (Regular) admitted from AY 2020-21 and B.Tech (Lateral Entry) from AY 2021-22, under RGM-R-2020. || ⚠️⚠️ THE CGPA THIS FORMULA CONVERTS IS NOT COMPUTED FROM ALL 160 CREDITS — UNIQUE IN THIS REGISTRY AND EASY TO GET WRONG. §7.4: 'The student shall register and put up minimum attendance in all 160 credits and earn 160 credits. GRADES OBTAINED IN 150 CREDITS (EXCLUDING THE CREDITS OBTAINED IN SKILL DEVELOPMENT COURSES/VALUE ADDED COURSES) SHALL BE CONSIDERED FOR THE CALCULATION OF CGPA.' The §11.0 class table likewise reads 'CGPA secured from 150 Credits'. FOR LATERAL ENTRY IT IS 111 CREDITS OF 121. A student recomputing CGPA across all credits will get a different figure from their grade card. || GRADE SCALE IS FINE-GRAINED WITH DECIMAL BOUNDARIES: O = 10 (90-100, Outstanding), A+ = 9 (80-89.9, Excellent), A = 8 (70-79.9, Very Good), B+ = 7 (60-69.9, Good), B = 6 (50-59.9, Above Average), C = 5 (45-49.9, Average), P = 4 (40-44.9, Pass), F = 0 (<40), Ab = 0. ⚠️ NOTE THE 5-MARK BANDS AT THE BOTTOM AND THAT P (PASS) CARRIES ONLY 4 POINTS — most colleges award 5 at the pass threshold. Minimum CGPA for the degree is 4.0 (§12.4), internally consistent with a 4-point pass grade. || CLASS IS AWARDED ON PERCENTAGE, NOT CGPA (§11.0): First Class with Distinction ≥ 70%; First Class 60–<70%; Second Class 50–<60%; Pass Class 40–<50%. The table carries a parallel CGPA column, but percentage is operative — which is why the conversion is stated 'for any academic/employment purpose'. || Skill Development and Value Added marks are excluded from the award of division (§12.3) though their credits count toward the degree.
