Thanks for your reply, but it does not answer my question…
Maybe I did not explain it clearly enough.
When product unit is Kg, I know the system will work as expected if I enter “2 Kg”, or “5 Kg”, or “0.1 Kg”… but it will set a wrong quantity for “250 gr” or “1/4 Kg” instead of “0.25 Kg”. That’s the reason I expected some format or syntax to separate labels and values in this field. With that, we could even use “Small box” as label and specify “0.33” Kg as quantity.
Thank you again
