88.0% is a B+.

How to use it

  1. Enter your percentage.
  2. See the letter grade and the 4.0-scale value; the table highlights your band.

The formula

93–100 = A (4.0), 90–92 = A- (3.7), 87–89 = B+ (3.3), 83–86 = B (3.0) …

Below 65 = F (0.0)

Good to know

  • To convert an average across many classes, convert each class first and then average the grade points — not the percentages.
  • Some schools use a 10-point scale (90–100 = A); check your handbook.
