Mexican grades to US GPA
Mexican universities grade from 5 to 10, with 6 as the minimum pass. An 8 average is a respectable record. Enter your promedio to see an estimated 4.0-scale GPA.

How the estimate works
The estimate draws straight lines between these points on the “Grade on the 5–10 scale” scale: 6 → 1.0, 8 → 3.0, 8.3 → 3.3, 8.6 → 3.7, 10 → 4.0. The points in the middle come from the published tables below; mapping the lowest pass to 1.0 and the top of the scale to 4.0 is a GradeKite assumption. Values outside the points get no estimate.

|---|---|
| Passing (6 to 10) | 6–10 |
| Not passed (NA) | 5 |
From letters to numbers at UNAM
UNAM’s General Examination Regulations express passing grades as the numbers 6, 7, 8, 9 and 10, with 6 as the minimum to pass a subject. A 5 means “no acreditada” (not passed), and NP marks a student who did not sit the exam. Earlier UNAM records used letters, and the same regulations give their numerical equivalents: MB (Muy Bien) = 10, B (Bien) = 8 and S (Suficiente) = 6; NA has no numerical equivalent. If an old transcript shows letters, convert them that way before averaging.
Most Mexican universities and the public school system use the same 5-to-10 frame, though each institution writes its own rules for rounding and averaging.
What foreign universities publish
The tables agree closely for Mexico. Toronto sets mid-B at 8.0, B+ at 8.3 and A− at 8.6. Oregon State asks for 8 out of 10 or 80% (“Bien”) for its B average. Loughborough puts a UK First at 8.5, a 2:1 at 8 and a 2:2 at 7 for a Licenciatura.
Worked example
Diego’s promedio is 8.5. On Toronto’s anchors it is two-thirds of the way from 8.3 (3.3) to 8.6 (3.7): 3.3 + 0.4 × 2/3 = 3.57, shown as 3.6. Loughborough reads 8.5 as a First, and it clears Oregon State’s 8. Because Toronto’s anchors are only 0.3 apart, small differences in a Mexican average move the estimate a lot: 8.2 gives 3.2, while 8.6 already gives 3.7.
Below 8, the line down to 6 (treated as 1.0) is a GradeKite assumption, not a published equivalence; a 7 estimates at 2.0.
