Country / scale context
The IB Diploma combines six subjects plus Theory of Knowledge and the Extended Essay for a maximum of 45 points. Universities publish their own IB offer conditions (e.g. 38 points with 6,6,6 at HL) rather than a single global percentage.
Important limitation
Credential evaluators (e.g. WES) and individual universities may apply course-by-course evaluation that differs from a single overall percentage mapping. Treat outputs as educational guidance for planning, not as an official evaluation report.
Frequently asked questions
Is this an official conversion from a credential evaluator?
No. It applies documented common conventions and cites them. Official WES / university evaluations can differ.
Can I convert both ways?
Yes — use the mode toggle above the inputs.
