How to Convert a Percentage to a Letter Grade
Converting a percentage to a letter grade or GPA requires mapping your score to a specific country's grading scale. Our converter uses the official educational guidelines from the US, UK, Australia, and India to provide an instant, simultaneous conversion. Simply enter your percentage, and we'll show you exactly how it translates internationally.
US Grading Scale — Percentage to Letter Grade Chart
The United States uses a 4.0 GPA scale and a standard letter grading system (A to F). Generally, an A is 90-100%, a B is 80-89%, a C is 70-79%, a D is 60-69%, and anything below 60% is an F. The exact mapping can vary slightly by high school or university, but this standard scale is accepted almost everywhere for general conversions.
UK Grading Scale — Percentage to Degree Classification
Universities in the United Kingdom use a degree classification system instead of GPAs. A score of 70% or higher is considered excellent and earns a "First Class Honours" (a First). 60-69% is an "Upper Second Class" (2:1), 50-59% is a "Lower Second Class" (2:2), and 40-49% is a "Third Class." In the UK, scoring above 80% is extremely rare and exceptional.
Australian Grading Scale — HD, D, C, P, F Explained
Australian universities use a banded system. An 85-100% is a High Distinction (HD), which is equivalent to an A+ in the US. A 75-84% is a Distinction (D), 65-74% is a Credit (C), and 50-64% is a Pass (P). Anything below 50% is a Fail (F).
India Grading Scale — Percentage to CGPA (10-point)
In India, the University Grants Commission (UGC) standardized a 10-point grading system. An 'O' (Outstanding) is 90-100% and carries 10 points. 'A+' (Excellent) is 80-89% with 9 points, and 'A' (Very Good) is 70-79% with 8 points. Converting Indian percentages directly to a US 4.0 GPA can be tricky, which is why services like WES exist, but our calculator gives you a highly accurate estimate based on standard admissions guidelines.

Divide your percentage by 9.5 to get a rough CGPA on the 10-point scale, or use the direct percentage-to-GPA mapping: 90%+ = 4.0, 85-89% = 3.7, 80-84% = 3.3, 75-79% = 3.0, 70-74% = 2.7. Note that US universities evaluate Indian transcripts holistically and often request WES evaluation for official conversions.
