12-Point GPA Scale Calculator & Conversion to 4.0 Scale / Percentage
Navigating different GPA systems can be confusing, especially if you’re dealing with transcripts from institutions using a 12-point scale, common in many Canadian universities. Our tool allows you to easily calculate your GPA on a 12-point scale or convert a 12-point GPA to the more common 4.0 scale or a percentage.

Understanding the 12-Point GPA Scale
Unlike the 4.0 scale which directly maps to letter grades (A=4.0, B=3.0, etc.), the 12-point scale offers more granularity. It’s often used to better represent a student’s standing within a letter grade. For example, instead of just an “A,” there might be an A+ (12), A (11), and A- (10). This system is prevalent in various regions, most notably at many post-secondary institutions in Ontario, Canada.

This conversion table provides a general guide for translating grades between systems. It’s important to note that the exact conversion can vary slightly by institution. For official purposes, always refer to the specific conversion scale provided by the institution or evaluation service (like WES).

Frequently Asked Questions (FAQ)
Why do I need to convert my GPA?
GPA conversion is often necessary when applying for graduate school, scholarships, or jobs, especially when the application system is based in a different country or region. For instance, a Canadian student applying to a US medical school would need to have their grades converted to the 4.0 scale used by AMCAS.
Is this conversion scale universal?
No, it is not universal. This chart represents a common conversion standard, often aligned with scales like the one used by the Ontario Medical School Application Service (OMSAS). However, individual universities can have their own unique scales. For example, some may cap their 4.0 scale at 4.3 (for an A+). Always check with the specific institution for their official policy. For a good example of an official policy, you can view the grading system of a major Canadian institution like the University of Toronto.
How do I calculate my GPA if I have grades from multiple schools with different scales?
This is a complex situation often handled by official transcript evaluation services like World Education Services (WES). They will convert all of your coursework to a single, standardized scale for a fee. For an informal calculation, you would need to convert each grade to a consistent scale (like the 4.0 scale) and then use a standard GPA calculator with the appropriate credit hours.
