Convert scores from the Indian system into the US 4.0 GPA scale. Scores between 8 and 10 are equal to a 4.0 on the U.S. scale. Scores between 6 and 7 are equal to a 3.0 on the U.S. scale. Scores of between 3 and 5 are equal to a 2.0 on the U.S. scale. Finally, scores between 1 and 2 are equal to a 1.0 on the U.S. scale. For example, if you have three grades, 8, 6, and 3 in the Indian system, you have a 4, 3 and 2 on the U.S. scale.
Add the converted scores together. For example, 4 + 3 + 2 = 9.
Divide the figure by the number of scores. For example 9 / 3 = 3. In this example, your GPA is a 3.0 in the U.S. scale.
