Converting GPA to percentage requires multiplying the GPA by a specific factor, commonly 9.5 or 10, to find the equivalent percentage. For example, a GPA of 3.0 multiplied by 9.5 gives 28.5%, while using 10 results in 30%. Similarly, a GPA of 3.5 converts to 33.25% with 9.5 or 35% with 10. A perfect GPA of 4.0 translates to 38% using the first factor and 40% with the second. The conversion method may vary based on the institution or region, so it's crucial to consult your educational institution's specific conversion scale for precise results.
