Many people have many thoughts about converting percentage scores to GPA scores. Most say for 4 GPA score, the equivalent percentage will be 100% => 4.0 GPA, 75% => 3.0, 50% => 2.0, and 25% => 1.0. But I don’t think such GPA conversion is a correct or the real one.

Here is the GPA conversion system which I found most trustworthy and genuine. It is published by Cascadia Community College in USA. Here is the conversion pattern:

0%-59% => 0 GPA
60% => 0.7 GPA
61% => 0.8 GPA
62% => 0.8 GPA
63% => 0.9 GPA
64% => 1.0 GPA
65% => 1.0 GPA
66% => 1.1 GPA
67% => 1.2 GPA
68% => 1.3 GPA
69% => 1.4 GPA
70% => 1.5 GPA
71% => 1.6 GPA
72% => 1.7 GPA
73% => 1.8 GPA
74% => 1.9 GPA
75% => 2.0 GPA
76% => 2.1 GPA
77% => 2.2 GPA
78% => 2.3 GPA
79% => 2.4 GPA
80% => 2.5 GPA
81% => 2.7 GPA
82% => 2.8 GPA
83% => 2.9 GPA
84% => 3.0 GPA
85% => 3.0 GPA
86% => 3.1 GPA
87% => 3.2 GPA
88% => 3.3 GPA
89% => 3.4 GPA
90% => 3.5 GPA
91% => 3.5 GPA
92% => 3.6 GPA
93% => 3.7 GPA
94% => 3.8 GPA
95% => 3.9 GPA
96% => 3.9 GPA
97% => 4.0 GPA
98% => 4.0 GPA
99% => 4.0 GPA
100% => 4.0 GPA

I hope this conversion pattern will help Indian, Nepali, Pakistani and other students who belong to country where scoring is done on percentage of total score.

Although it is used as the most appropriate percentage to GPA conversion table by most universities, top universities in USA, UK, Australia, and Canada have their own unique algorithm to determine actual GPAs of the students. Such algorithms, used to calculate the GPAs of students from different countries, are made after in-depth research of that specific country's academic standard, academic syllabus, highest scores obtained, etc. It is therefore advised not to convert your percentage to Grade Point Average (GPA) on your own; instead, ask the institution you’re applying to about how much your percentage converts to in their GPA system.

According to SAIT in Alberta Canada the grading system is as follows:

90-100% ------ A+ ------ 4.0
85- 89% ------- A ------ 4.0
80- 84% ------- A- ------ 3.7
77- 79% ------- B+ ------ 3.3
73- 76% ------- B ------ 3.0
70- 72% ------- B- ------ 2.7
67- 69% ------- C+ ------ 2.3
63- 66% ------- C ------ 2.0
60- 62% ------- C- ------ 1.7
55- 59% ------- D+ ------ 1.3
50- 54% ------- D ------ 1.0
0 - 49% ------- F ------ 0
