China GPA Converter (百分制 → GPA)
Convert a Chinese 0–100 percentage score (百分制) to a GPA / 绩点 under your chosen method, with the Chinese descriptor band. Indicative — each university's table varies.
Calculator
indicative: Indicative only: China has no single national GPA scale — each university registrar varies. Use your own institution's published table for official records.

About this calculator
This converter turns a Chinese 百分制 (0–100 percentage) score into a GPA / 绩点 under the conversion method you select, and shows the fixed Chinese descriptor band (优秀 / 良好 / 中等 / 及格 / 不及格). China has no single national GPA formula — every university registrar publishes its own table, and credential evaluators such as WES apply their own algorithms. So every result here is INDICATIVE and institution-varies: use it to understand the mapping, not as an official transcript figure. Choose “single score” to convert one mark, or “weighted GPA” to enter several courses with credits and get a credit-weighted 加权平均绩点.
How to read your results
The headline is the grade point (绩点) for your score on the chosen scale, shown as “GP / scale max” (for example 3.81 / 4.0). Beside it is the Chinese descriptor for that percentage and the scale you picked. In weighted mode you also get the credit-weighted GPA, the weighted-average percentage, and a per-course bar so you can see which courses lift or lower the average. The reference table lists the full band-to-grade-point mapping for the selected method. Every figure carries an indicative / institution-varies note.
How it's calculated
For the non-linear 4.0 method, scores X ≥ 60 map to GP = 4 − 3·(100 − X)² / 1600 and scores below 60 map to 0 (so 100 → 4.0, 90 → 3.8125, 80 → 3.25, 70 → 2.3125, 60 → 1.0). The standard 4.0, 4.3 and 5.0 methods use inclusive band tables looked up by percentage. The Chinese descriptor is a fixed band: 优秀 90–100, 良好 80–89, 中等 70–79, 及格 60–69, 不及格 below 60. Weighted GPA is the credit-weighted mean of the per-course grade points, GPA = Σ(credits × GP) ÷ Σ(credits), and the weighted-average percentage is Σ(credits × score) ÷ Σ(credits). Scores are clamped to 0–100 and credits must be greater than 0. Every output is indicative and institution-varies — China publishes no single national GPA scale.
Worked example
Two courses under the non-linear 4.0 method: 90% (4 credits) and 80% (2 credits).
Grade points: 90% → 4 − 3·(100−90)²/1600 = 3.8125; 80% → 4 − 3·(100−80)²/1600 = 3.25. Weighted GPA = (4×3.8125 + 2×3.25) ÷ 6 = 3.625 on the 4.0 scale. The weighted-average percentage is (90×4 + 80×2) ÷ 6 = 86.7%, whose descriptor is 良好 (Good). Heavier courses move the GPA more than lighter ones.
Frequently asked questions
Why are there four different methods?
Because China has no single national GPA scale. The non-linear 4.0 (“Algorithm Two”, GP = 4 − 3·(100−X)²/1600 for X ≥ 60) is the WES-cited curve used by universities such as Peking and Zhejiang. The standard 4.0 band is the coarse mapping (90–100 → 4.0, 80–89 → 3.0, and so on) many evaluators use. The 4.3 scale adds an A+ ceiling, and the 5.0 scale is used by some institutions. Pick the one your registrar or evaluator uses; all four are indicative.
What do 优秀 / 良好 / 中等 / 及格 / 不及格 mean?
They are the fixed Chinese descriptor bands by percentage: 优秀 (Excellent) 90–100, 良好 (Good) 80–89, 中等 (Fair/Medium) 70–79, 及格 (Pass) 60–69, and 不及格 (Fail) below 60. These bands are stable across most Chinese institutions even though the GPA conversion is not, so the converter always shows the descriptor alongside the grade point.
How is the weighted GPA (加权平均绩点) calculated?
Each course’s percentage is converted to a grade point under the chosen method, then the credit-weighted mean is taken: GPA = Σ(credits × grade point) ÷ Σ(credits). The converter also reports the credit-weighted average percentage Σ(credits × score) ÷ Σ(credits) and the descriptor for that average, so you can cross-check both views. Credits must be greater than 0.
Can I use this result for admissions or WES?
No. It is an educational estimate, not an official conversion. WES and other credential evaluators compute their own GPA from your full transcript using their internal algorithm, and each university registrar has its own table. Always use your institution’s published scale and the evaluator’s own output for official purposes.
What happens below 60?
A percentage below 60 is 不及格 (Fail) and maps to a grade point of 0 on every method here. On the non-linear curve the formula only applies at 60 and above; below 60 the grade point is 0 rather than a negative value.
