Convert academic grades between US, UK, European (ECTS), and Indian grading systems.
Useful for study abroad and international applications.

Grade Equivalents

Grade scale conversion translates grades between different systems — letter grades (A, B, C), percentage scores, GPA (0–4.0 or 0–10), and international grading systems used around the world.

US Letter Grade to GPA (4.0 Scale):

Letter Grade Percentage 4.0 GPA
A+ 97–100% 4.0
A 93–96% 4.0
A− 90–92% 3.7
B+ 87–89% 3.3
B 83–86% 3.0
B− 80–82% 2.7
C+ 77–79% 2.3
C 73–76% 2.0
D 60–69% 1.0
F Below 60% 0.0

GPA Calculation Formula:

GPA = Sum(Grade points × Credit hours) / Total credit hours

Worked Example:

Course Credits Letter Grade Grade Points
Math 3 A (4.0) 12.0
English 3 B+ (3.3) 9.9
History 2 A− (3.7) 7.4
Chemistry 4 B (3.0) 12.0

Total grade points = 41.3 ÷ 12 total credits = GPA: 3.44

International Equivalents:

System Equivalent to US “A”
UK First Class (70%+)
Germany 1.0–1.5 (scale inverted)
France 16–20 / 20
India 90%+ (distinction)

Practical Tips:

  • Different institutions weight A+ differently — check your school’s exact scale
  • Weighted GPA adds 0.5–1.0 point for AP/IB courses; colleges recalculate to unweighted for comparison
