⚠️ Important Information
Understanding GPA Conversions
Grade conversion between different education systems is not standardized globally. Different universities and organizations may use slightly different conversion scales. Our calculators use the most commonly accepted conversion standards, but always verify with your target institution's specific requirements.
For Official Applications
When applying to universities or for official purposes, always use official transcript evaluation services like WES, ECE, or your institution's designated evaluator. Our calculators provide estimates for planning and reference purposes.
Weighted vs Unweighted GPA
Weighted GPA accounts for course difficulty (AP, IB, Honors) with bonus points, potentially exceeding 4.0. Unweighted GPA uses standard 4.0 scale for all courses. College applications often require both - check which your target schools prefer.
