Frequently Asked Questions
How do you convert percentage to letter grades?
The standard scale is: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%. Some schools use plus/minus grades (A− = 87–89%, B+ = 87–89%) which adjust the ranges slightly.
What is GPA equivalent?
GPA equivalent represents what grade point value your percentage would translate to on a 4.0 scale. For example, an A (90–100%) = 4.0 GPA, B (80–89%) = 3.0 GPA, and so on.
What if my school uses a different grading scale?
This calculator uses the standard US grading scale. If your school uses a different scale (like 93–100% for A), you may need to adjust the percentage thresholds, but the conversion method remains the same.
How many points do I need to improve my grade?
This calculator shows how many more points you'd need to reach the next letter grade threshold. For instance, if you're at 85% (B), you'd need 5 more points to reach 90% (A).
Can I use this for weighted assignments?
This calculator is best for single assignment grades. For weighted course grades where different assignments have different percentages, calculate your weighted average first, then enter that as your points earned.
