GPA to Percentage Conversion Chart
Convert a US 4.0 GPA back to an approximate percentage range. Note that GPA bands represent a range — the midpoint is shown as the approximate equivalent.
UK Degree Classification to GPA Conversion
How UK undergraduate degree classifications map to the US 4.0 GPA scale. Commonly needed for US graduate school applications and international job applications.
Note: These are generally accepted equivalencies. Some US graduate schools and employers use slightly different scales. WES (World Education Services) is the standard for official credential evaluation.
IB Score to GPA Conversion
The International Baccalaureate uses a 1–7 scale per subject. This table shows how each IB grade maps to the US 4.0 GPA scale and letter grade system.
Note: IB total diploma scores (24–45 points) are different from individual subject scores. Individual subject scores on the 1–7 scale are what this table converts.
Frequently Asked Questions
Common questions about GPA conversions and grading systems.
How do I convert a percentage to a GPA?
Divide your percentage into bands and match each band to a GPA value on the 4.0 scale. For example, 93–100% = 4.0 (A), 90–92% = 3.7 (A−), 87–89% = 3.3 (B+), and so on down to below 60% = 0.0 (F). Use the percentage to GPA table on this page for the full conversion.
What is a 3.5 GPA as a percentage?
A 3.5 GPA falls between a B+ and an A−, which corresponds to approximately 87–92% on the percentage scale. The midpoint is roughly 90%. Because GPA is reported in discrete bands, there is no single exact percentage equivalent — 3.5 represents a range of roughly 87–92%.
What is a 3.0 GPA as a percentage?
A 3.0 GPA corresponds to a B, which is the 83–86% range on the standard percentage scale. The approximate midpoint is 85%.
How does a UK 2:1 convert to a US GPA?
A UK Upper Second Class Honours (2:1) is generally considered equivalent to a US GPA of approximately 3.3–3.7, with 3.5 being the most commonly cited conversion. A First Class degree (1st) equates to a 4.0, and a Lower Second (2:2) equates to approximately 2.7–3.0.
How does an IB score convert to a GPA?
The IB uses a 1–7 scale per subject. An IB 7 (Excellent) equals a 4.0 GPA, an IB 6 (Very Good) equals 3.7, an IB 5 (Good) equals 3.3, an IB 4 (Satisfactory) equals 3.0, an IB 3 (Mediocre) equals 2.0, and IB scores of 1–2 fall below a 2.0.
Is GPA used outside the United States?
The 4.0 GPA scale is primarily used in the United States and Canada. The UK uses degree classifications (First, 2:1, 2:2, Third). Most European countries use percentage or letter systems. Australia uses a High Distinction / Distinction / Credit / Pass system. The IB uses a 1–7 scale. When applying to US graduate schools from abroad, you will typically need to convert your grades to the 4.0 scale.
Are GPA conversions exact?
No — GPA conversions are approximate. Different institutions use slightly different conversion scales, and there is no single universal standard. The conversions on this page follow the most widely accepted US academic standards. For official applications, always check the specific institution's conversion policy or use WES (World Education Services) for an official evaluation.

Converting a percentage to GPA is one of the most common needs for students applying to US graduate programs from abroad. A grade of 85% typically converts to a 3.0 GPA, while 93% and above equals a 4.0. Use the GPA calculator if you need to calculate your GPA from individual course grades instead.
UK students applying to US universities often need to convert their degree classification to a GPA equivalent. A First Class Honours degree generally converts to a 4.0 GPA, while an Upper Second Class (2:1) is typically equivalent to a 3.3–3.7. These are widely accepted equivalencies — for official applications, WES (World Education Services) provides formal credential evaluations.
IB students can use the IB to GPA conversion table to see how their 1–7 subject scores map to the US letter grade and 4.0 GPA system. An IB score of 7 equals a 4.0 GPA, and an IB score of 4 is roughly equivalent to a 3.0. Note that individual subject scores are different from your total IB diploma score.
