All Academic Calculators
Everything on the site, grouped. The quickest way to pick: a grade is one course, a GPA is several courses averaged by credit, and a converter moves a number you already have onto a different scale.
Each tool runs in your browser, keeps your work in local storage on your own device, and asks for nothing. Two focused hubs sit under this one: grade calculators and GPA calculators and converters. Cards marked “Soon” are on the roadmap and not yet built.

How these tools relate to each other
Most confusion about grade maths comes from mixing up three separate questions. What did I score? is a grade — one course, one number, worked out either from weighted categories or from plain points. Where do I stand overall? is a GPA — several courses averaged together and weighted by credit, so a five-credit course moves it more than a one-credit course does. What is this number on another scale? is a conversion, and it never creates new information; it only restates what you already have.
A practical consequence: never average percentages when you mean to add points, and never average GPAs when you mean to average courses. Both mistakes quietly treat a small assignment as equal to a large one. Each tool here is built around one of those three questions, and the page you land on will say which model it is using.
Everything runs client-side. Your scores stay in your own browser's storage, nothing is sent to a server, and no tool asks you to sign in. Cards marked “Soon” are planned rather than built — they are shown so you can see what is coming, and they are deliberately not clickable.
