Common GPA conversions across grade scales

Always verify with your school's published grade-to-points table. Some schools use modified scales (e.g., 95+ for A, no A+, or A+ = 4.33).

The basics

What is GPA?

Grade Point Average (GPA) is the credit-weighted average of your letter grades converted to point values. It is the single most-quoted academic number in US education — used for college admissions, scholarships, internship applications, honor societies, and grad school decisions.

The math is simple but multi-step: each grade has a point value, each course has a credit weight, and your GPA is a credit-weighted average. A 3-credit A and a 1-credit C average out closer to the A than to the C because the A is worth more credits.

The math

The formula

GPA = Σ (grade points × credits) / Σ credits

Walk through it course by course: multiply each grade's point value by its credit hours, sum those products, then divide by the total credits. The single most common mistake is averaging GPAs instead of credit-weighting them.

Worked example

Three courses, one semester:

  • Calculus I: A (4.0) × 4 credits = 16.0 quality points
  • English 101: B+ (3.3) × 3 credits = 9.9 quality points
  • Art appreciation: A- (3.7) × 2 credits = 7.4 quality points
  • Total: 33.3 quality points / 9 credits = 3.70 GPA

High school basics

Weighted vs unweighted GPA

High schools that offer Advanced Placement (AP), International Baccalaureate (IB), or Honors classes often use a weighted GPA scale. The system rewards harder courses with extra points:

  • Regular course: A = 4.0
  • Honors course: A = 4.5 (+0.5 bonus)
  • AP or IB course: A = 5.0 (+1.0 bonus)

A weighted GPA can exceed 4.0 — students at academically competitive high schools commonly graduate with 4.3-4.8 weighted GPAs. Unweighted GPA caps at 4.0 regardless of course difficulty.

Which one do colleges look at?

Most US colleges recalculate GPA using their own formula. They want to see both the weighted GPA (rigour signal) and the actual transcript (course list). Submitting a 4.5 weighted GPA with no AP courses raises questions; a 3.7 unweighted with 8 AP courses is much more impressive.

When you're applying abroad

GPA grading scales worldwide

United States

4.0 scale (with +/- modifiers in college). High school sometimes uses 5.0 weighted. A=4.0, B=3.0, etc.

Canada

Varies by province and school. Some use 4.0, some 4.3 (A+ = 4.3), some 9.0 or 12.0 scales (Quebec).

UK

Honors degree classification: First (70%+), Upper Second / 2:1 (60-69%), Lower Second / 2:2 (50-59%), Third (40-49%). Not GPA-based.

Australia

GPA on a 7.0 scale at most universities (HD=7, D=6, C=5, P=4, etc.). Some use 4.0.

Germany

1.0 (best) to 4.0 (passing), with 5.0 = fail. Inverted from US — lower is better. A 1.5 German is roughly a 3.5 US.

India

Most universities use a 10-point CGPA (Cumulative GPA). 10 = perfect, 9+ excellent, 6 minimum pass. Direct conversion to US: roughly divide by 2.5.

Use the official conversion

When applying to international schools, use the school's official conversion table — never a generic online converter. The same letter grade can map to different point values depending on the country and discipline.

Tracking the long game

Cumulative GPA across semesters

Cumulative GPA is your GPA across all completed semesters. The calculator handles this when you add multiple semesters: it sums all quality points across every course and divides by total credits across every semester.

A common mistake: averaging semester GPAs equally. A 4.0 semester (12 credits) and a 3.0 semester (18 credits) does NOT average to 3.5. The credit-weighted average is (4.0 × 12 + 3.0 × 18) / 30 = 3.4. The bigger semester pulls the average more.

Common questions

How do I improve my GPA?

Your existing credit total dilutes any single new grade. If you have 60 credits at 3.0 and you take 12 more credits at 4.0, your new cumulative GPA is (60 × 3.0 + 12 × 4.0) / 72 = 3.17. To move from 3.0 to 3.5, you'd need 60 more credits of 4.0 work.

What is a good college GPA?

Highly subjective. 3.0+ is the typical employer floor. 3.5+ is common for grad school applications. 3.7+ for selective grad programs. 3.9+ for top-tier programs. Bear in mind: GPA is one signal among many (test scores, extracurriculars, recommendations).

Should pass/fail courses count?

Usually no — they're excluded from GPA calculation because they don't have a numerical grade. Some schools count "Pass" as a C for major requirements but exclude it from GPA. Check your school's policy.

What about transfer credits?

Policies vary. Many US universities accept transfer credits (the course counts toward your degree) but exclude the grade from your GPA calculation. So a transfer A doesn't help your GPA, but a transfer F doesn't hurt it either. Check the registrar.

Is GPA the same as a percentage?

No, but they correlate. US schools generally use 90+ = A, 80+ = B, 70+ = C, 60+ = D, <60 = F. A 3.5 GPA at one school might map to 88% average; at a school with strict grading, 84%.

Can my GPA go above 4.0?

Only on weighted scales. On a 4.0 unweighted scale, no — A and A+ both count as 4.0. On a 4.3 scale, A+ counts as 4.3 so an all-A+ semester gives you 4.3. On a 5.0 weighted scale, AP and IB courses can push you above 4.0.

Quick steps

1

Pick a grade scale

4.0 standard, 4.0 with plus/minus, 4.3 (A+ counts higher), or 5.0 weighted for high-school AP/IB/Honors.

2

Enter your courses

Course name is optional. Credits and letter grade are what matters. On the weighted 5.0 scale, mark each course as Regular, Honors, or AP/IB.

Frequently asked questions

How is GPA calculated?

Each grade has a point value (A=4.0, B=3.0, etc.). Multiply each grade's points by the credit hours, sum all those products, then divide by the total credit hours. That's a credit-weighted average.

What's the difference between weighted and unweighted GPA?

Unweighted GPA caps at 4.0 — an A is 4.0 whether the course is regular or AP. Weighted GPA gives bonus points for harder courses (typically +1.0 for AP/IB, +0.5 for Honors), so an A in AP Calc counts as 5.0. Weighted GPAs above 4.0 are common at academically rigorous high schools.

Which grade scale should I use?

Use what your school uses. 4.0 standard is rare today; most US colleges use 4.0 with +/-. Canadian and some Asian universities use 4.3 (A+ worth more). US high schools with AP/IB use weighted 5.0. Check your school's policy.

How do I calculate cumulative GPA across semesters?

Sum all quality points (grade × credits) across every semester, then divide by total credits. Our tool does this automatically when you add multiple semesters.

What is a 'good' GPA?

Depends on context. For US college admissions, a 3.5 unweighted is competitive at most schools, 3.8+ for selective. For grad school, 3.5+ is generally required. For high school graduation, 2.0 is typically the minimum.
