GPA Scale: Complete Letter Grade & Percentage Conversion Chart

The GPA scale you use depends on your country, school, and program. This guide covers every major scale used worldwide — from the standard US 4.0 scale to Australia's 7-point system, India's 10-point CGPA, and France's 20-point marks — with full conversion tables and a built-in converter.

Standard US 4.0 GPA Scale

The 4.0 scale is the most widely used in the United States and Canada. Each letter grade corresponds to a grade point, and your GPA is the credit-weighted average of those points.

Letter Grade Percentage Grade Points (4.0)
A+97 – 1004.0
A93 – 964.0
A−90 – 923.7
B+87 – 893.3
B83 – 863.0
B−80 – 822.7
C+77 – 792.3
C73 – 762.0
C−70 – 721.7
D+67 – 691.3
D65 – 661.0
FBelow 650.0

Note: some US universities use the 4.3 scale, which distinguishes A+ (4.3) from A (4.0). Always check your institution's official scale.

GPA Scales Around the World

An "A" grade doesn't mean the same number everywhere. Here's how the top grade maps across the major scales:

4.3 Scale (US With A+)

Some US schools — along with Hong Kong universities — add a distinct A+ grade worth 4.3 points, allowing students to exceed a "perfect" 4.0 GPA in courses where A+ is awarded.

4.5 Scale (South Korea)

Used by most Korean universities. Top grade is A+ = 4.5. Passing is typically D = 1.0. Seoul National University (SNU) is a notable exception that uses the 4.3 scale instead.

5.0 Scale (Singapore NUS / NTU)

Used by NUS, NTU, SUTD, SUSS, and SIT in Singapore, plus some Malaysian universities. Note that SMU in Singapore actually uses the 4.0 scale instead, and all five Singapore polytechnics use 4.0.

7.0 Scale (Australia — GPA / WAM)

Standard at most Australian universities. Often called "GPA" (4-point weighted) or "WAM" (Weighted Average Mark out of 100) depending on context. The 7-point GPA below is the most common reporting format.

10.0 Scale (India / Pakistan CGPA)

Used by IITs, NITs, and most universities across India, Pakistan, and Bangladesh. Grades are expressed as CGPA (Cumulative Grade Point Average) on a 10-point scale.

A+Excellent9.0

20-Point Scale (France / Lebanon)

French, Lebanese, and Belgian universities mark students out of 20. 10 is usually the passing threshold and anything 16+ is considered excellent — a mark of 20 is extremely rare and reserved for near-perfect work.

Mark (out of 20)Description
16 – 20Très Bien (Excellent)
14 – 15Bien (Good)
12 – 13Assez Bien (Fair)
10 – 11Passable (Pass)
0 – 9Insuffisant (Fail)

Percentage Scale (UK / China)

UK universities mark out of 100, with a degree classification attached at the end. Chinese universities typically use the same 0–100 scale directly as the GPA.

UK MarkClassification
70 – 100First Class Honours (1st)
60 – 69Upper Second Class (2:1)
50 – 59Lower Second Class (2:2)

Converting Your GPA Between Scales

The safest rule is percentage-based conversion: divide your GPA by the max of your current scale to get a percentage, then multiply by the target scale's max.

For example, converting a 3.6 on a 4.0 scale to a 5.0 scale:

3.6 ÷ 4.0 = 90%  →  90% × 5.0 = 4.5 on the 5.0 scale

This is an approximation. For official admissions conversions (US graduate schools especially), institutions often use WES (World Education Services) or their own internal policy.

Weighted vs Unweighted GPA (AP / Honors)

In the US, many high schools give a "weighted" GPA for AP and Honors courses — a bonus added on top of the standard 4.0 scale to reflect the higher difficulty.

Course TypeA Grade = Grade Points
Regular course4.0
Honors course4.5
AP / IB course5.0

This is why you sometimes see US high school GPAs reported as 4.3, 4.5, or even 5.0 — these are weighted values. Colleges typically "unweight" back to the 4.0 scale when comparing applicants.

GPA Scale FAQ

Which GPA scale should I use?

Use whatever scale your school officially reports. If you're applying to a school that uses a different scale, convert using percentage-based conversion (GPA ÷ current scale max × target scale max). Most US graduate admissions rely on WES conversions for international transcripts.

Is a 4.3 scale harder than a 4.0 scale?

Not harder — just more granular. A 4.3 scale lets schools distinguish A+ performance (4.3) from regular A (4.0). If you never get A+ grades, your GPA looks the same on both. The difference only appears when converting: a 4.0 on the 4.3 scale corresponds to a 3.72 on a 4.0 scale (4.0 ÷ 4.3 = 93%, × 4.0 = 3.72).

How is the 5.0 Singapore scale different from a 5.0 weighted US scale?

The Singapore 5.0 scale is a native grading system (A+/A = 5.0, A− = 4.5, B+ = 4.0 …). The US "weighted 5.0" is an AP/Honors bonus added onto a base 4.0 scale. They look similar but map to different underlying grades.

Why does Australia use a 7-point scale instead of 4-point?

Australian universities use High Distinction (HD = 7), Distinction (6), Credit (5), Pass (4), and Fail (0). This mirrors the original British honours classification more closely than the US 4-point GPA. Australian students can convert to a US 4.0 equivalent by dividing by 7 and multiplying by 4.

Is a GPA the same thing as a CGPA?

Functionally yes — a CGPA (Cumulative GPA) is just a GPA calculated across all completed semesters rather than a single term. The term "CGPA" is dominant in India, Pakistan, Bangladesh, Malaysia, and the Middle East; "GPA" is more common in the US.
