Here’s the standard 4.0 GPA scale most frequently used by US based high schools and colleges:

Letter Grade | Percent Grade | 4.0 Scale |
---|---|---|

A+ | 97-100 | |

A | 93-96 | |

A- | 90-92 | |

B+ | 87-89 | |

B | 83-86 | |

B- | 80-82 | |

C+ | 77-79 | |

C | 73-76 | |

C- | 70-72 | |

D+ | 67-69 | |

D | 65-66 | |

E/F | Under 65 | 0.0 |

**Unweighted GPA Scale:**

Most colleges and school report GPA on a 4.0 scale. The unweighted GPA scale is the most frequently used GPA scale**.** Basically, the highest GPA you can earn is a 4.0, which indicates an A average in all of your classes. A 3.0 would mean a B average, a 2.0 a C average, a 1.0 a D, and a 0.0 an F. This scale does not take the difficulty of your course. For example, if you’re in all Advanced Placement or Honors classes and earn a B+ , you’ll have the same GPA as someone in all low-level classes who has earned a B+.

**Weighted GPA Scale:**

The unweighted GPA scale goes up to a 4.0 and doesn’t factor in class difficulty. A weighted GPA scale typically goes up to a 5.0 and does consider the difficulty of a course. For example – students get an extra 1.0 added to the unweighted GPA value of their grades for high level classes like honors or AP. So, on a weighted scale A B in an honors class would be equivalent to a 4.0 on a weighted GPA scale, and an A would be equivalent to a 5.0.

Also, some schools also offer mid-high level courses that sits between honors and low-level classes. 0.5 points are usually added to the unweighted GPA for those courses, meaning an A would be equivalent to a 4.5. Grades in low-level classes are measured using the unweighted standard scale, so an A in those classes would be equivalent to a 4.0.

**GPA Scale – FAQs**

**How does the GPA scale work?**

There are two types of GPA scales (weighted and unweighted), and they work differently. An unweighted GPA scale is based on a 4.0 scale. Regardless of the type of course, regular or advanced, an A is worth 4 points. Bs are worth 3 points. Cs are worth 2 points. Ds are worth 1 point. Fs aren’t worth any points. When using an unweighted GPA scale, the highest GPA one can receive is a 4.0. In a weighted GPA scale, Advanced Placement (AP) or Honors Courses are worth more than regular courses. In a weighted GPA scale, an A is worth 5 points. Bs are worth 4 points. Cs are worth 3 points. Ds are worth 2 points. Fs are not worth any points. When using a weighted GPA scale, GPAs can be higher than a 4.0, possibly all the way up to a 5.0.

**How do you convert percentage to GPA?**

To convert percentages to GPA, you must assign each percentage a letter grade. Typically, 90-100% is an A. 80-89% is a B. 70-79% is a C. 60-69% is a D. 0-59% is an F. An A is worth 4 points. Bs are worth 3 points. Cs are worth 2 points. Ds are worth 1 point. Fs aren’t worth any points. Add up all your points for your letter grades for each semester and divide by the number of semester grades. That is your GPA.

**How do you convert letter grade to GPA?**

To convert letter grades to GPA, you must assign each letter grade a point value. An A is worth 4 points. Bs are worth 3 points. Cs are worth 2 points. Ds are worth 1 point. Fs aren’t worth any points. Add up all your points for your letter grades for each semester and divide by the number of semester grades. That is your GPA.

**How do percentage grades convert to letter grades and then to GPA?**

The conversion from percentage grades to letter grades, and subsequently to GPA, involves a standardized scale. Here’s a general overview:

**Percentage to Letter Grade**: Schools often have a chart that matches a range of percentages with letter grades (e.g., 90-100% = A).**Letter Grade to GPA**: Each letter grade corresponds to a specific value on the GPA scale (e.g., A = 4.0)

**How are GPA scales adjusted for different school policies? **

Different schools may have unique policies for converting percentage grades to letter grades and then to GPA points. Some schools might use a plus/minus system within the letter grade scale (e.g., B+, B, B-), each with its corresponding GPA value, while others may not. Schools may also vary in the minimum percentage required for each letter grade. It’s important to consult your institution’s specific grading policy to understand how your grades translate into GPA.
