Weighted average, grading scales, grade conversion — 100% local.

Add one row per student or assessment, with its grade and weight (1 by default).

Points needed

Full grading scale

Standard "scale with a pass threshold" method: from 0 points to the threshold, the grade increases linearly from 1 to 4; from the threshold to the total points, it increases from 4 to 6.

Pass

Reference points

Standard linear conversion: 6/6 = 20/20 = 100%, 1/6 = 0/20 = 0%. The Swiss pass threshold (4/6) therefore corresponds to 12/20 and 60% — for comparison, the usual French threshold is 10/20 (50%): the two systems don't use the same threshold, so the conversion doesn't automatically align them. Some school or cantonal grading scales may also differ slightly — always check with your institution for an official result.

All calculations are performed entirely in your browser.

The weighted average

A weighted average multiplies each mark by its weight, adds it all up, then divides by the sum of the weights — not by the number of marks.

average = Σ(mark × weight) ÷ Σ(weight)

A test marked 4 with weight 3 counts as much as three quizzes marked 4 with weight 1. Useful for giving a final exam more weight than homework.

The "with-threshold" grading scale

Many Swiss teachers don't use a plain linear scale (where half the points would give the mark 4). The "with-threshold" model sets a points threshold for reaching the pass mark, then joins two line segments: from 0 points to the threshold, the mark rises from 1 to 4; from the threshold to the maximum, it rises from 4 to 6. So it usually takes more than 50 % of the points to pass, reflecting the expected level of demand.

Converting between grading systems

Switzerland (/6)France (/20)Percentage
6.020.0100%
4.0 (CH pass)12.060%
3.510.0 (FR pass)50%
1.00.00%
Caution: the conversion is purely linear (6/6 = 20/20, 1/6 = 0/20). It does not align the pass thresholds: 4/6 equals 12/20, whereas the usual French bar is 10/20. A Swiss "pass" is not a French "pass".

Frequently asked questions

Are the mark lists stored?

No. Everything is computed in your browser and nothing is transmitted. Closing the tab clears the entered data.

Can I use it for an official report?

It's a calculation aid. Your school's or canton's official scale always takes precedence — check the threshold and rounding used by your institution.

Which rounding should I choose?

The quarter point is the most common in French-speaking Switzerland, the half point elsewhere. The tool offers both, plus the tenth.
