Worked example

The official Central University of Jharkhand (CUJ), Ranchi formula is Piecewise (official): ≥8.5 → 80+(CGPA−8.5)×10; 7.5–8.49 → 70+(CGPA−7.5)×10; 6.5–7.49 → 60+(CGPA−6.5)×10; 5.5–6.49 → 55+(CGPA−5.5)×5; 4.5–5.49 → 50+(CGPA−4.5)×5; 4.0–4.49 → 45+(CGPA−4.0)×10; 3.0–3.99 → 35+(CGPA−3.0)×10; 2.5–2.99 → 30+(CGPA−2.5)×10; 2.0–2.49 → 25+(CGPA−2.0)×10; 1.0–1.99 → 15+(CGPA−1.0)×10; 0.0–0.99 → (CGPA−0.5)×15. Starting from a percentage of 57.5%, the formula reverses to a CGPA of about 6 on the 10-point scale.

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

Central University of Jharkhand — Controller of Examinations, 'TO WHOM IT MAY CONCERN', Ref. No. CUJ/COE/2020/259/(V-06)/8494 dated 30-03-2026: 'It is hereby notified to all the concerned students that Conversion Formula from CGPA to Percentage is as follows' — table 'Conversion Formula from CGPA to Percentage' (11 bands, as in the formula field); Explanatory Note: '1. For example, if a student has obtained a CGPA of 6.00, his percentage is 55 + (6-5.50) x 5 = 55 + 0.50 x 5 = 55 + 2.50 = 57.50. 2. Similarly, if a student has obtained a CGPA of 4.38, his percentage is 45 + (4.38-4.00) x 10 = 45 + 0.38 x 10 = 45 + 3.80 = 48.80.'

OFFICIAL PIECEWISE FORMULA (not a single multiplier). The notice is scanned and was read on screen; its explanatory examples confirm the ×5 slope in the 5.5–6.49 band (6.00 → 57.50%). The notice says the certificate will not be issued to individual candidates and should be downloaded from the website. EARLIER VERSION: the University's NAAC SSR (2019, Criterion 2.5.4) printed the same bands but with ×10 in the 5.5–6.49 and 4.5–5.49 bands, which created jumps at 5.5 and 6.5 (e.g. 6.49 → 64.9% but 6.5 → 60%). The 2026 notice (×5) removes those jumps and supersedes the SSR text. Oddity kept as printed: the lowest band is '0 + (CGPA − 0.5) × 15' for 0.0–0.99, which is negative below 0.5 (clamped to 0 here) and jumps from 7.35% at 0.99 to 15% at 1.0. Fail-range only; it doesn't affect passing students. Master's ordinance (OA-11): First Division ≥ 60% or equivalent grade; Second Division ≥ 50%. CUJ is unitary (no affiliated colleges).
