Weighted to Unweighted GPA Converter
Instantly convert your weighted GPA to the standard unweighted 4.0 scale using the same proportional formula colleges use. Supports 5.0, 6.0, and 4.5 weighted scales.
This tool is for high school students applying to college, scholarship applicants, and anyone who needs to report their GPA on the standard 4.0 unweighted scale.
Weighted to Unweighted GPA Conversion Chart
The table below shows equivalent unweighted 4.0 GPA values for common weighted GPA scores across the three supported scales — 5.0, 4.5, and 6.0. Use it as a quick reference before using the converter above.
| Weighted GPA | 5.0 → 4.0 | 4.5 → 4.0 | 6.0 → 4.0 | Academic Standing |
|---|---|---|---|---|
| 5.0 / 4.5 / 6.0 | 4.00 | 4.00 | 4.00 | Exceptional |
| 4.8 / 4.3 / 5.7 | 3.84 | 3.82 | 3.80 | Outstanding |
| 4.5 / 4.0 / 5.4 | 3.60 | 3.56 | 3.60 | Excellent |
| 4.0 / 3.6 / 4.8 | 3.20 | 3.20 | 3.20 | Above Average |
| 3.5 / 3.1 / 4.2 | 2.80 | 2.76 | 2.80 | Average |
| 3.0 / 2.7 / 3.6 | 2.40 | 2.40 | 2.40 | Below Average |
| 2.5 / 2.2 / 3.0 | 2.00 | 1.96 | 2.00 | Needs Improvement |
How to Convert Weighted GPA to Unweighted GPA
A weighted GPA accounts for course difficulty by adding bonus grade points to advanced classes. Most US high schools add +0.5 for Honors courses and +1.0 for AP or IB courses on a 5.0 scale. For example, earning an A in an AP course earns 5.0 grade points instead of 4.0. This rewards students who challenge themselves with rigorous coursework. The exact bonus amount depends on your school's specific grading policy — some districts use a 6.0 scale where AP earns 6.0 for an A.
An unweighted GPA uses a strict 4.0 scale regardless of course difficulty. Every class — whether regular, Honors, or AP — is graded the same way: an A earns 4.0, a B earns 3.0, a C earns 2.0, and so on. Unweighted GPA is the most widely recognized standard used by colleges, employers, and scholarship organizations to compare students on equal footing. You can calculate yours using our unweighted GPA calculator.
The proportional conversion formula works in three steps:
- Identify your weighted scale maximum — 5.0, 4.5, or 6.0 depending on your school's policy.
- Divide your weighted GPA by the scale maximum — this gives you the proportional position on the scale (e.g. 4.5 ÷ 5.0 = 0.90).
- Multiply by 4.0 — this converts the proportion to the 4.0 scale (0.90 × 4.0 = 3.60). Cap the result at 4.0 if it exceeds that value.
5.0 scale: Unweighted = (Weighted ÷ 5.0) × 4.0
6.0 scale: Unweighted = (Weighted ÷ 6.0) × 4.0
4.5 scale: Unweighted = (Weighted ÷ 4.5) × 4.0
Many colleges and universities recalculate high school GPA on their own internal scale during the admissions process. This is because grading standards, course offerings, and weighting policies differ drastically between high schools. A 4.5 weighted GPA from one school may reflect entirely different coursework than a 4.5 from another. By standardizing to an unweighted 4.0 scale, admissions officers can compare students fairly across thousands of high schools. Knowing your unweighted GPA in advance also helps you assess your competitiveness and identify the right target schools.
Why Convert Weighted GPA to Unweighted?
There are three situations where knowing your unweighted GPA is not just useful — it is essential. Each scenario below involves an audience that expects the standard 4.0 scale.
Weighted vs Unweighted GPA — Key Differences
| Aspect | Weighted GPA | Unweighted GPA |
|---|---|---|
| Definition | GPA that includes bonus points for advanced courses | GPA calculated on a strict equal-weight basis |
| Scale | Typically 5.0 (AP/IB), 4.5 (Honors), or 6.0 | Standard 4.0 scale |
| Accounts for Course Difficulty | Yes — rewards AP, IB, and Honors enrollment | No — all courses treated equally |
| Used By | High schools to reflect course rigor on transcripts | Colleges, scholarships, and employers as the standard |
| Typical Range | 0.0 to 5.0 (or 6.0 depending on school policy) | 0.0 to 4.0 |
| Best For | Showing academic ambition and course selection rigor | Comparing students across different schools fairly |

Pro Tip
Always report both your weighted and unweighted GPA on college applications if the form allows it. Your weighted GPA demonstrates course rigor, while your unweighted GPA provides the standardized benchmark admissions offices use. Use our weighted grade calculator to explore how individual course grades affect your overall weighted GPA. You can also convert your CGPA to GPA or check the full GPA scale guide for more context.
