How to Convert Between GPA Scales
Different countries use different grading scales, which creates confusion for students applying to universities abroad. Here are the core conversion formulas this tool uses:
For the Australian 7-point and UK classification scales, conversion uses grade band mapping rather than linear formulas. A US 4.0 maps to a 7 (High Distinction) in Australia and a First Class in the UK. A 3.5 maps to approximately 6 (Distinction) and Upper Second (2:1) respectively.
If you need to convert a percentage grade instead, our percentage to GPA calculator handles the standard US grading scale lookup automatically. For a full reference of how letter grades map across systems, see our grading scale guide.
Why GPA Conversions Are Approximations, Not Exact
No GPA conversion formula is perfectly precise. Different countries grade differently in fundamental ways: the US system uses letter grades with a 4.0 ceiling, India uses a 10-point cumulative system, and the UK uses broad classifications (First, 2:1, 2:2, Third). A 3.5 GPA in the US does not mean exactly the same thing as an 8.75 CGPA in India or a Distinction in Australia.
Grading curves, course difficulty, and institutional standards all vary. A 3.5 from a highly competitive engineering program may represent stronger performance than a 3.8 from a less rigorous institution. Universities understand this, which is why many have their own internal conversion policies.
This tool provides the standard mathematical conversion that most grade converter tools and reference tables use. However, your target university may apply a different formula. Always check with the admissions office before relying on any conversion for formal applications. For US-specific calculations, try our GPA calculator or college GPA calculator.
Quick Tips
- Check your target university first. Many universities publish their own conversion chart on their admissions page, and that chart overrides any standard formula.
- Select the right source scale. Some systems include +/- grades (US 4.3 scale) and some do not (US 4.0). Choosing the wrong source scale changes the conversion.
- Ask the admissions office. When applying internationally, ask which scale the university prefers. Some want your original percentage, others want a converted 4.0 GPA.
