How does the Brazilian 0-10 scale map to a US GPA?

There is no single official table, but a common linear mapping treats 10-9 as 4.0 (A), 8.x as 3.5, 7.x as 3.0 (B), 6.x as 2.5, the pass mark to 5.9 as 2.0 (C), and anything below the pass mark as 0.0 (F). This tool uses a piecewise mapping anchored to your chosen pass mark.

Should I use a pass mark of 5.0 or 6.0?

It depends on your university. Many federal universities pass at 6.0 (or 7.0), while some private institutions pass at 5.0. Choose the value printed in your academic regulations so failing grades convert to 0.0 correctly.

Nota is Portuguese for grade or mark. Brazilian transcripts list each course's nota on a 0 to 10 continuous scale, often to one decimal place.

Why is the conversion only an estimate?

Different US institutions use different equivalence tables, and a continuous 0-10 scale does not map cleanly onto discrete US letter grades. Use the result for planning and confirm the official method with your target university or an evaluation service like WES.

Brazilian university grade conversion

Brazilian universities grade on a continuous 0 to 10 scale (the nota), with the pass mark set by each institution at typically 5.0, 6.0, or 7.0. To apply to a US program you need that expressed as a 4.0 GPA. This converter applies a piecewise mapping anchored to your pass mark and weights the result by credit hours.

How it works

The tool maps each nota to a US grade point using these bands (pass mark = P):

9.0 - 10.0   ->  4.0  (A)
8.0 - 8.9    ->  3.5  (A-/B+)
7.0 - 7.9    ->  3.0  (B)
6.0 - 6.9    ->  2.5  (B-/C+)
P   - 5.9    ->  2.0  (C)
below P      ->  0.0  (F)

When the pass mark is 6.0, any grade below 6.0 is a fail and maps to 0.0; the 6.0-6.9 band then represents the lowest passing grades. When the pass mark is 5.0, grades from 5.0 to 5.9 pass and map to 2.0.

The weighted GPA is:

GPA = sum(gradePoint_i * credits_i) / sum(credits_i)

Rows with no grade or no credits are ignored.

Tips and notes

If your university uses concept grades (A, B, C, D, E) instead of numbers, convert them to the middle of each band first.
Brazilian credit hours (creditos) often equal weekly contact hours; use whatever weighting your transcript provides.
For official admissions, a credential evaluation service applies its own table, so treat this as a planning figure.
