Frequently Asked Questions
Q: What grading scale does this converter use?
A: This converter uses a simple A/B/C/D/F scale: A for 90-100, B for 80-89, C for 70-79, D for 60-69, and F below 60.
Q: Why can grading scales vary by school or teacher?
A: Schools sometimes use plus and minus grades, weighted systems, or custom cutoffs. This converter stays with one clear baseline scale so the result is easy to read.
Q: Can I use decimal percentages?
A: Yes. Decimal percentages are accepted, and the grade is assigned according to the same score ranges.
Q: What happens at the cutoff values?
A: The converter treats the cutoff as part of the higher grade band, so 90 is an A, 80 is a B, 70 is a C, and 60 is a D.
Q: Why does 59% still show F here?
A: Under this simple scale, anything below 60 falls in the F range. Some schools may apply other rules, but this converter uses the straightforward baseline.
Q: When is this useful?
A: It is useful for quick score checks, report summaries, classroom planning, and turning raw percentages into an easy grade label.
