GPA Calculator
📐 GPA Calculator
Convert a percentage score into GPA on the US 4.0 scale, the 10-point scale common in India, or a 5-point scale — useful for university applications that ask for an unfamiliar grading format.
The 4.0 scale conversion follows the standard US letter-grade bands (A=4.0, A−=3.7, B+=3.3, and so on), rather than a straight linear percentage-to-GPA ratio — which is why the relationship isn't perfectly proportional across the full range.
Frequently Asked Questions
Is the 4.0 GPA conversion exact?
It follows the most common US letter-grade-to-GPA mapping, but individual universities sometimes use slightly different bands — treat this as a close estimate for forms that ask for an equivalent GPA.
Why isn't the conversion a straight line?
Because the underlying letter-grade bands aren't evenly spaced — the gap between an A and A− differs from the gap between a C+ and C, for instance, which the formula reflects.
Which scale should I use for a US university application?
Use the 4.0 scale — it's the standard US convention. Many international applicants also list their original percentage alongside the converted GPA for clarity.
