# GPA percentage conversion: How do I convert a 3.8 GPA to a 100-scale?

I've got a 3.8 GPA, but some colleges I'm applying to use a 100-point scale. Can anyone help me convert my GPA? What's the best method to use for an accurate calculation?

To convert your 3.8 GPA to a 100-point scale, you can use the following general method: first, determine the percentage range associated with each letter grade at your school, and then find the percentage that corresponds to your 3.8 GPA within that range.

Most high schools use a standard 4.0 scale with the following breakdown:

- A (4.0) = 90%-100%

- B (3.0) = 80%-89%

- C (2.0) = 70%-79%

- D (1.0) = 60%-69%

- F (0.0) = below 60%

From this letter grade range, your 3.8 GPA should fall between an A- and an A. Here's how to convert that to a percentage on a 100-point scale:

1. Determine the lower and upper percentage limits of an A- and A:

- A-: 3.67 = 90%

- A: 4.0 = 100%

2. Find the difference in GPA points between your GPA and the lower limit:

3.8 - 3.67 = 0.13

3. Find the difference in percentage points between the lower and upper limit:

100 - 90 = 10

4. Divide the difference in GPA points by the total GPA range and multiply by the percentage range:

(0.13 / 0.33) 10 = 3.94 (approximately)

5. Add the resulting value to the lower percentage limit:

90 + 3.94 = 93.94 (approximately)

So, your converted GPA on a 100-point scale would be approximately 93.94%. Keep in mind that this is just a general method and individual schools might have different grading scales. It's always best to check with your high school or the colleges you're applying to for specific information on their conversion methods.
