So - do your users enter some data into the form? Like, looking at this table:
1000ml/l X 30L = 30000 ml
6.1g/L X 30L = 183g
8.5 g/L X30L= 255g
50 g/L X 30L = 1500g
20g/L X 30L =600g
50g/L X 30L = 1500g
Do the users enter (or select from a dropdown) 1000ml/l? or 6.1g/L? and you need to show the value on the other side of the equal sign in the form in another field? Can the user enter any data they chose? Or will it always be one of the options from your table?
