Turning a rating of 5 into a score out of 20
The method for establishing a score out of 20 begins with the determination of the conversion coefficientfound by dividing the highest number by the lowest, i.e. 20 by 5, giving a coefficient of 4.
Thus :
- To convert a rating of 15 out of 20 into a rating out of 5, simply divide 15 by 4which gives 3.75.
- In the opposite direction, to transpose a score of 3 out of 5 into a score out of 20, it is necessary to multiply 3 by 4, resulting in 12.

- If you convert a rating of 15 out of 20 into a score out of 10, you'll get 7.5 out of 10, knowing that 15/2 = 7.5.

Extending an assessment from 20 to 30 and vice versa
In this scenario, the application of proportionality rule (or cross product) is relevant. The idea is to find the value "n" that represents the score out of 30. Let's take the example of an assessment of 10 out of 20 to be converted into a rating out of 30, the method is as follows:
- From 10 → to 20; From n → to 30; let's calculate n = 10 x 30 / 20, resulting in a score of 15. Thus, a score of 10 out of 20 is equivalent to 15 out of 30.
This same formula is reversible to establish a score out of 20. For a rating of 15 out of 30, the calculation is as follows:
- From 15 → to 30; From n → to 20. The value is only obtained by n = 15 x 20 / 30, giving a score of 10.
Turning a rating of 20 into a mark out of 40 and vice versa
Know that :
- To transform a 20-point evaluation into a 40-point scale, the principle of the conversion coefficient (40/20 = 2) is applied. So, to go from a mark out of 20 to a mark out of 40, simply use the multiplier by 2.
- On the other hand, to convert a mark out of 40 into a mark out of 20, it will be necessary to divide the score by the same coefficient.
Here's a table with examples to illustrate these two cases.
| 🎯 Note | 🔎 Equivalence |
| 15 sur 20 | 30 of 40 |
| 20 of 40 | 10 out of 20 |
