A letter GPA scale maps each letter grade to grade points — A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with +/- steps. If you’re asking what is GPA scale in short: it’s the ruler your GPA is measured with.

What is GPA scale reporting?
GPA scale reporting is how a school states which scale a GPA is on — 4.0, 4.5, or 5.0 — so colleges can compare fairly. Always report your GPA with its scale.
Which GPA scale does my school use?
Most US schools use 4.0; many use 5.0 for weighted GPAs. Check your transcript or ask your counselor — the scale is usually printed next to the GPA.

Does the converter handle percentages?
Yes — pick 100% as the “from” scale and enter your percentage; the converter maps it to a letter grade, then to 4.0, 4.5, and 5.0.
