Grade Calculator – Custom or Verified Scale | MZ Smart Tools House
Convert a percentage to a letter grade only after selecting a verified university policy or a clearly labeled custom manual grading scale.
University grade boundaries differ. This calculator never silently treats one generic table as an official policy.
How it works
The entered percentage is matched against the selected policy or custom percentage band.
Example
If your selected scale defines 90–100 as A, 90 falls in that band. Different scales may produce a different letter grade.
Frequently asked questions
Does MZ use one universal grading table?
No. Official-university conversion is enabled only for explicitly verified policies; custom mode is user-defined.
Can I use my own grading scale?
Yes. Select the custom manual scale and edit the percentage bands to match the policy you have verified.
