I am currently trying to use the formula column to add 20KG to a number if a value is present.

“if({weight(unpacked)} is “something” then + 20KG”)

The formula column should output the SUM of weight(unpacked) + 20KG, for example if weight(unpacked) were 100KG the formula column should output 120KG.

And is there a way to have the KG after the value.
