Converting your GPA from a letter grade to a decimal can be especially important when applying to colleges or for scholarships, so it’s important to get it right. With a little bit of math, you’ll be able to easily convert your grades and get a better understanding of your academic performance.

What is GPA?

If you’re a student, you’ve probably heard of GPA. It stands for Grade Point Average and is a measure of your academic performance.

GPA is a way for colleges and universities to evaluate your academic achievements and determine your eligibility for admission, scholarships, and other academic opportunities.

Understanding GPA is important for any student who wants to succeed academically. By knowing how GPA is calculated and what it means, you can set goals for yourself and work towards improving your academic performance.

Here are some key things to know about GPA:

  • GPA is usually calculated on a scale of 0.0 to 4.0, with 4.0 being the highest possible GPA.
  • Letter grades are typically converted to a numerical value on this scale. For example, an A is usually worth 4.0 points, a B is worth 3.0 points, and so on.
  • Some schools may use a different grading scale or have different values assigned to each letter grade. It’s important to check with your school to understand how GPA is calculated.
  • GPA is calculated by dividing the total number of quality points by the total number of GPA hours. Quality points are the numerical values assigned to each letter grade (e.g. an A is worth 4.0 quality points). GPA hours are the number of credit hours for each course.
  • GPA can be calculated for a single semester or for your entire academic career. Your cumulative GPA is your overall GPA for all courses taken.
  • GPA can be unweighted or weighted. An unweighted GPA is calculated based on the standard 4.0 scale. A weighted GPA takes into account the difficulty of your courses and assigns extra points for advanced or honors courses.

How is GPA Calculated and Converted to Decimal?

Calculating your GPA can seem like a daunting task, but it’s actually a straightforward process.

Important Factors

Here’s what you need to know:

  • Credit Hours: Each course you take is worth a certain number of credit hours. The credit hours are determined by the number of hours you spend in class each week. For example, a three-credit-hour course meets for three hours each week.
  • Grade Points: Each letter grade you receive is assigned a certain number of grade points. For example, an A is worth 4.0-grade points, while a B is worth 3.0 grade points.
  • GPA Calculation: To calculate your GPA, you need to multiply the number of credit hours for each course by the grade points for that course. Add up all of these values, and then divide by the total number of credit hours you’ve taken.
  • GPA Scale: The GPA scale ranges from 0.0 to 4.0, with 4.0 being the highest possible GPA. Your GPA is an important factor in college admissions, as it gives colleges a sense of your academic performance.
  • Decimal Place: Your GPA is typically calculated to two decimal places. However, some schools may calculate your GPA to more decimal places for accuracy.
  • Conversion Table: To convert your letter grades to grade points, you can use a conversion table. Different schools may use slightly different conversion tables, so be sure to check with your school to see what table they use.


So how exactly is GPA calculated?

The formula for calculating GPA varies slightly depending on the school. But generally, it involves multiplying the numerical value of each letter grade by the number of credit hours for the class, adding up all of those values, and then dividing by the total number of credit hours.

For example:

  1. If you received an A in a 3-credit class, your quality points would be 12 (the numerical value of an A) multiplied by 3, which equals 36.
  2. If you received a B in a 4-credit class, your quality points would be 9 (the numerical value of a B) multiplied by 4, which equals 36.
  3. Add those two values together (36 + 36) and divide by the total credit hours (7), and your GPA for those two classes would be 5.14 on a 4.0 scale.

What Are the Different Types of GPA?

When it comes to calculating GPA, there are different types of systems in use. Here are the most common types of GPA:

Unweighted GPA

This GPA is the most common type of GPA used in high schools and colleges. It is based on a 4.0 scale and assigns a numerical value to each letter grade. The values are:

  • A = 4.0
  • B = 3.0
  • C = 2.0
  • D = 1.0
  • F = 0.0

An unweighted GPA treats all classes the same, regardless of their level of difficulty. It is a simple way of calculating GPA and is used by most colleges and universities.

Weighted GPA

A weighted GPA is a grading system that takes into account the difficulty of the classes you take. It’s similar to an unweighted GPA, but assigns extra points to classes that are considered more challenging, such as honors, AP, or IB classes.

The values for a weighted GPA are the same as for an unweighted GPA, but the extra points can raise your GPA above 4.0. This can be a great way to showcase your academic achievements and stand out to colleges or employers. By taking more challenging classes and earning good grades, you can improve your weighted GPA and demonstrate your academic potential.

Pass/No Pass GPA

Pass/No Pass GPA is a grading system used for courses that are not required for your degree program or for courses that are taken for personal interest. With this system, you will either pass or fail the course, instead of receiving a letter grade. If you pass, you will receive a P, which is equivalent to a 4.0. If you fail, you will receive an N, which is equivalent to a 0.0.

This option can be a great way to explore new interests or take courses outside of your major without worrying about the impact on your GPA. However, it’s important to note that some graduate programs or employers may view Pass/No Pass grades differently than letter grades, so it’s important to consider this when deciding whether to take a course on a Pass/No Pass basis.

Ultimately, the Pass/No Pass option can be a useful tool for students looking to broaden their academic horizons while still maintaining their GPA.

Honors GPA

Honors GPA is a grading system that recognizes students who have successfully completed more rigorous courses than the standard level, but not as advanced as AP or IB courses. These courses are usually weighted, meaning they carry more value than regular courses, but not as heavily as AP or IB courses.

The calculation of an Honors GPA is similar to that of a weighted GPA, but the assigned values for honors courses are different from those given to AP and IB courses. This means that while honors courses will still contribute to your GPA, they will not have as significant an impact as AP or IB courses.

By understanding the differences between these grading systems, you can better understand your academic performance and how it compares to other students.


When it comes to gauging academic rigor, institutions turn to AP/IB GPAs. AP and IB refer to Advanced Placement and International Baccalaureate, respectively. These programs are crafted to replicate college-level courses and carry the most weight when calculating academic success.

When it comes to calculating your AP/IB GPA, the process is similar to that of a weighted GPA. However, the key difference lies in the values assigned to AP/IB classes versus honors classes.

Since AP/IB classes are considered more rigorous than honors classes, they are given a higher numerical value when calculating your GPA. This means that your AP/IB classes will have a greater impact on your overall GPA than your honors classes.
