@Daniel , the snag with eJuice Me Up is also that it does not save the settings as a default seperate to the saved recipes.
Once you set the grams initially as @RichJB explained, save it as part of the default setting for when next you enter a recipe from scratch - Use File -> Save As Default (Ctrl-D) and overwrite the Default.dft file in the location where it was installed.
You'll unfortunately also have to redo the setting of weights every time for every existing recipe you open and will need to save them again to retain the weights.
Juice Calculator on the other hand has a very nice interface (once you figure it out) for ingredients and manufacturers, and saves the weight with the ingredient. It will also default the weights for you when you add a new one, and has the ability to check and keep track of your stock.
