Why these specific cutoffs?

The 90/80/70/60 cutoff system is the unofficial standard for US K-12 schools and most universities. It dates back to the 1970s when statisticians at the College Board recommended it as a balance between meaningfulness and simplicity. The +/− modifiers (A-, B+, etc.) were added in the 1980s and 90s to give a finer-grained 12-band scale within the 4.0 system.

Schools that don\u2019t use plus/minus

A small but meaningful number of universities — including most of the University of California system — do not use +/− modifiers in their GPA calculations. On those scales, every A is a 4.0 (89.5%+), every B is a 3.0 (79.5–89.4%), and so on. This is mathematically simpler and slightly more generous in the upper bands.

The 4.33 scale

A handful of universities (notably some Canadian schools and US graduate programs) use a 4.33 ceiling, awarding 4.33 points for A+. This rewards perfectionism without inflating the rest of the scale. If you are reporting a 4.33-scale GPA on a graduate application, list both your raw 4.33 GPA and a note about your school\u2019s scale — admissions committees almost always normalize back to 4.0 for comparison.

Frequently asked questions

What does a 3.5 GPA equal in percentage?

A 3.5 corresponds to roughly an 88–89%, which falls into the B+ band on the standard scale. Different universities apply slightly different cutoffs — our converter uses the most common 90/80/70/60 system.

Why do schools use different scales?

There is no national standard. Some schools use 4.0 caps, some use 4.33 (with A+ at 4.33), some use 5.0 (with weighting). Internationally, scales range from German 1.0–5.0 (lower is better) to Indian CGPA out of 10. Our scale converter handles all of them.

Can I get a 4.33 GPA?

Only at schools that use the 4.33 scale. On that scale, an A+ is 4.33 and an A is 4.0; everything else mirrors the standard 4.0 system. Most schools cap A+ at 4.0 to keep the maximum at 4.0.

How do I convert percentage to GPA?

Use the standard cutoff table: 93%+ = A (4.0), 90–92% = A- (3.7), 87–89% = B+ (3.3), and so on down to F. Our converter does this automatically — type a percentage and the GPA appears.
