Understanding Grade Conversions
Grade conversions are essential for international students, transfer students, and anyone comparing their academic performance across different grading systems. Each country and institution may use slightly different scales, so these conversions serve as general guidelines.
Common Conversion Methods
Percentage → Letter Grade
The most straightforward conversion. In a typical US system:
- 90–100% = A range
- 80–89% = B range
- 70–79% = C range
- 60–69% = D range
- Below 60% = F
Letter Grade → GPA
Each letter grade maps to grade points on the 4.0 scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus/minus modifiers adjust by ±0.3.
International Conversions
Converting between the 4.0 (US), 5.0, and 10.0 (India) scales requires care. There is no perfect mathematical formula—each scale was designed independently. Our converter uses commonly accepted equivalencies. For official purposes, use a credential evaluation service like WES. See our detailed conversion guide.
FAQ
No. These are standard approximations used widely across US institutions. Individual schools may have different breakpoints. For official conversions (especially for international transcripts), use credential evaluation services like WES, ECE, or SpanTran.
Most US universities cap the 4.0 scale at 4.0 for an A. Some schools do award 4.3 for an A+, but this is less common. Our converter uses the standard 4.0 cap for both A+ and A.
