Like pharmlover22 mentioned above, it's really a mystery since the Department does not do any of the conversions. You could refer to the one UBC MED uses but use caution.
Quoted from the Physiotherapy Department: "As universities and colleges have varying grade point scales, all grades will be converted to percentage using grade conversion tables provided to us by UBC Enrolment Services and/or information found on the back of official transcripts. The Admissions Office does not disclose its grading conversion tables to applicants. Official English translations are required for all Foreign transcripts that are not already in English." (

Regardless, prepare for the worst case scenario and move forward with that in mind.
