I have encountered a problem regarding a conversion between mS and S (millisiemens and Siemens) SI unit.
Let's say the result is 1000 mS m^2 mol^-1 and now I want to convert it to 1 S m^2 mol^-1. (we know that 1000 mS = 1 S).
When the 1 S m^2 mol^-1 is entered in the number and unit box I don't receive any score for this.
I tried searching through moodleformulas.org but unfortunately didn't find any solution for this. There is probably some sort of rule I don't know.
P.S. I have attached the .xml question for you to try.
