Important Note

The conversion from 100-point scale to 4.0 scale is not a direct one-to-one mapping. Different institutions may use slightly different conversion methods, so the results may vary slightly depending on the institution's specific grading policies.

Common Conversion Ranges

Here's a general guideline for converting between the two scales:

100-point scale: 90-100 → 4.0 GPA
100-point scale: 80-89 → 3.0-3.9 GPA
100-point scale: 70-79 → 2.0-2.9 GPA
100-point scale: 60-69 → 1.0-1.9 GPA
100-point scale: Below 60 → 0.0-0.9 GPA

Conversion Formula

The formula to convert a GPA from the 100-point scale to the 4.0 scale is:

Formula

GPA (4.0) = (GPA (100) / 25)

This formula works by dividing your 100-point GPA by 25, which effectively scales the 100-point range down to the 4.0 range. For example:

A 100-point GPA of 85 would convert to (85/25) = 3.4 on the 4.0 scale.
A 100-point GPA of 72 would convert to (72/25) = 2.88, which rounds to 2.9 on the 4.0 scale.

Rounding

When converting, it's common to round the result to one decimal place. For example, 2.88 becomes 2.9.

Worked Examples

Let's look at a few examples to see how the conversion works in practice.

Example 1: Excellent Student

You have a 100-point GPA of 92. Using the formula:

GPA (4.0) = 92 / 25 = 3.68

Rounded to one decimal place, your 4.0 GPA is 3.7.

Example 2: Average Student

You have a 100-point GPA of 75. Using the formula:

GPA (4.0) = 75 / 25 = 3.0

Your 4.0 GPA is exactly 3.0.

Example 3: Below Average Student

You have a 100-point GPA of 68. Using the formula:

GPA (4.0) = 68 / 25 = 2.72

Rounded to one decimal place, your 4.0 GPA is 2.7.

FAQ

Is the conversion from 100-point to 4.0 GPA exact?

The conversion formula provides a close approximation, but different institutions may use slightly different methods. Always check with your institution for their specific conversion guidelines.

How do I round the converted GPA?
