Grade to Letter Grade Calculator

Why do grading scales differ between countries?

Historical, cultural, and academic tradition differences led each country to develop its own grading system. The US uses an A–F letter system, the UK uses degree classifications (First, 2:1, 2:2, Third), India uses a 10-point CGPA or percentage system, and Australia uses HD/D/C/P/F. International students and employers need to convert grades between systems when comparing qualifications.

Is a 2:1 UK degree the same as a US B?

A UK 2:1 (60–69%) is roughly equivalent to a US B or B+. However, the comparison is imperfect because UK marking tends to be stricter — a 70% in the UK (First Class) is considered exceptional, while 70% in the US is a C. This calculator provides approximate equivalents for quick reference.

What is a GPA on a 4.0 scale?

The 4.0 GPA scale converts letter grades to numerical points: A=4.0, B=3.0, C=2.0, D=1.0, F=0. Most US universities require a minimum GPA of 2.0 to remain enrolled and a 3.0+ for graduate school competitiveness. Plus/minus grades create finer gradations (A−=3.7, B+=3.3, etc.).
