How to pick the right one
If you're not sure which tool fits, the homepage has a short “which calculator do I need?” guide organised by situation. For background on how grading and conversions work, the guides section has plain-English explainers, each linked to the calculator that does the work. And if a university you need isn't covered yet, tell us — ideally with a link to its official conversion circular, since we build every formula from a primary source.
