Configurable grade scales

Calculations stay in your browser. No account needed.

These are configurable mathematical scales, not official academic equivalences. Confirm weighting, pass rules, GPA table and rounding with your institution.

No student names are needed. Grades remain in this tab; nothing is saved automatically. Exports contain your inputs and results in plain text.

Formula & example

Choose editable starting bounds such as 0–20,0–10 or an inverted 1–6 scale. The calculator positions a grade between your bounds and interpolates to a target interval that you enter. For example 15 on 0–20 lies at 75% of that interval; it is not a certified equivalent grade in another country. In an inverted 1–6 scale,1 is the best boundary and 6 the worst. Real pass thresholds and grade distributions may be nonlinear: use your school’s actual rules rather than this interpolation.

p = (g − a) / (b − a); p↓ = 1 − p

15 ∈ [0,20] → p = 75%
