How to Convert Grades to US GPA
Converting your academic transcript to a US GPA scale is one of the most important steps for international students applying to American universities. Different countries use entirely different grading systems — some rely on percentage scores, others on letter grades, classification bands, or a 10-point scale. GradeAtlas provides accurate, university-specific grade mappings so you can calculate your equivalent GPA with confidence.
Whether you need a CGPA to GPA converter for a 10-point Indian university system, a percentage-to-GPA calculator for a European transcript, or a weighted GPA calculator for AP and IB courses, our tools handle the complexity behind the scenes. Every conversion is backed by official grading scales from over 246 countries and 1,159 distinct grading systems.
Why Accurate GPA Calculations Matter
Admissions committees and scholarship providers often set minimum GPA thresholds. An incorrect conversion can mean the difference between meeting a cutoff or being disqualified. Our country-specific grading guides include detailed conversion logic, honor classifications, and institutional notes so you understand not just the number but what it represents in your home education system.
