Example of something to keep in mind: if a recipe calls for 100grams of onion, you'll want to convert that into something useful for grocery shopping.
Probably good to instead talk about a measure of an onion for groceries. You won't be buying a 100 g onion, so you'll want to have 1 onion, regardless of size and know you'll have left-over onion for your omelette the next day. Because you need about 1/4 of a small onion, or whatever of a big onion. But if you need an amount of grams o' onion that requires a large onion, then you'll want a way to say a large onion. Or two small onions. Or whatever. Knowing you'll be doing a little bit of rough math at the grocery store. Your grocery list will get messy if you have 1 small onion and 1 large onion when the onions are in a bag. All of that to say, don't be to quick to start building everything in TW until you can visualize (spreadsheet or whatever) get a somewhat reasonable amount of "stuff" for the big picture. This process will help you decide to what degree of complex you want, and how/what/where to simplify when you don't want to get that bogged down in complexity, yadda yadda.
