Hi guys! I need your help
I want to transform data (Weight and Height), to make a new variable BMI, but I do not know what to put in the rule engine below
Hi @Jack_Lim
If you want to make a calculation, the Math Forumla node is the best choice. Since I don’t know in which units your height and weight are measured, I can’t give an example of how to make the calculation.

The only thing I’d add to what @HansS has said is that if somehow the bmi calculation is different between men and women, so you need a different calculation according to the value of the sex column, then you may find the new Expression node (KNIME 5.3 onwards) useful, as the Math Formula cannot “see” string variables. What version of KNIME are you using?
