Formula
On the US plus/minus scale the bands are 0.3 points apart: for example 87-89% is a B+ worth 3.3, and 90-92% is an A- worth 3.7.
Worked example
A score of 88% falls in the B+ band, so it converts to a GPA of 3.3 on the US scale. The same 88% is an A in Canada, worth 4.0, and a High Distinction in Australia, worth 7.0 on that scale. The country of the receiving institution decides which number belongs on the form.
Good to know
A single percentage converts cleanly because it belongs to exactly one band. Converting an overall percentage average is an approximation, though: a transcript average of 88% built from marks of 95% and 81% would produce a slightly different true GPA than one built from two 88s, because the grade points are averaged after banding, not before. For a full transcript, enter each course in the GPA Calculator instead.
