How to use it

  1. Enter the percentage, or the score as points earned over points possible, like 45/50.

The grading scale

On the most common US scale, 90–100% is an A, 80–89% a B, 70–79% a C, 60–69% a D and below 60% an F. Plus and minus split each band: 97% and up is an A+, 93–96% an A and 90–92% an A-, and B, C and D split the same way.

Some schools leave out plus and minus, and some use a 7-point scale where an A starts at 93%, a B at 85%, a C at 77% and a D at 70%. Pick a scale above to see its chart.

What percent is an A?

On the standard scale an A is 93–96%, an A- is 90–92% and an A+ is 97% and up, so any score from 90% is some kind of A. On a 7-point scale an A needs 93%.

In a GPA, an A and an A+ are both worth 4.0 points and an A- is worth 3.7.

Turning a score into a percentage

Divide the points earned by the points possible and multiply by 100. 45 out of 50 is 90%, an A-. 37 out of 45 is 82.2%, a B-.
