Frequently asked questions
Is this an official Japan conversion?
No. Universities and evaluators (e.g. WES, ECE) apply their own formulas — treat this as a guide.
How do I get my US GPA first?
Use the GPA calculator for one term or the cumulative GPA calculator across your degree.
Why are conversions only approximate?
Grading scales differ in shape and meaning between countries, so any mapping is an estimate.
