GPA scales differ fundamentally: 4.0 is the unweighted standard (A=4.0), 5.0 weights AP/IB courses (AP A=5.0, regular A=4.0), and percentage scales (0–100) underlie both. Convert via percentage as intermediate: to percent then to target scale — e.g. 3.5 on 4.0 = 87.5% = 4.375 on 5.0.
Letter-grade anchors help: A 90–100% = 4.0 (weighted 5.0), B 80–89% = 3.0 (weighted 4.0), C 70–79% = 2.0 (3.0 weighted), with plus/minus variants shifting by 0.3. Weighted scales add a full point for AP/IB, so a transcript mixing regular and AP courses needs course-by-course conversion, not a single multiplier.
Why schools invented weighted scales: to reward rigor without penalizing GPA when students take harder courses. The trade-off is non-comparability — a 4.3 on a 5.0 scale is not "better" than 3.9 on 4.0; both convert to ~86–88%. Colleges recalculate to their own scales, which is why the Common App asks for your school's scale plus unweighted GPA.
International pitfalls: Indian percentages, UK classifications (First/2:1), German 1.0–6.0 inverted scales, and French 0–20 all map differently. Direct GPA-to-GPA conversion without percentage and institutional context misrepresents achievement across systems.
Precision warnings: using linear percent-to-GPA (e.g. 85% = 3.4) ignores school-specific curves where 85% might be B+ = 3.3 at one school and A− = 3.7 at another. Always use the official transcript conversion for applications — this tool estimates for planning.
Use cases beyond admissions: scholarship cutoffs, athletic eligibility, honor rolls and employer screens often set GPA thresholds on a specific scale. Convert early to know whether you clear the bar on the scale that decision-maker uses.
For graduate admissions, many programs recalculate using only last 60 credits or core major GPA — convert both cumulative and major-specific GPAs when thresholds differ.
For graduate and scholarship thresholds, many programs recalculate using only the last 60 credits or core major GPA, ignoring early general-education grades. Convert both cumulative and major-specific GPAs when thresholds differ — a 3.2 cumulative with a 3.7 major may clear a 3.5 major cutoff despite missing the cumulative mark. When in doubt, ask the admissions office which pool they recalculate.
Weighted versus unweighted reporting strategy: some high schools report both, and the Common App lets you list weighted alongside your school profile. When a scholarship sets a 3.5 cutoff without specifying scale, assume unweighted and convert — a 4.1 weighted that is 3.4 unweighted may miss a 3.5 unweighted bar.
Convert GPA between 4.0, 5.0 and percentage scales — see equivalent GPA and letter grade. Formula: Convert via percentage: 4.0->% = (gpa/4)*100, 5.0->% = (gpa/5)*100, then %->4.0 = %/100*4. Example: 3.5 on 4.0 = 87.5% = 4.375 on 5.0.

3.5 on 4.0 = 87.5% = 4.375 on 5.0. An 85% average converts to ~3.4 on 4.0 but course-by-course weighting may yield 3.3–3.7 depending on plus/minus curves.
