Jumping ahead, I want a plugin that automatically applies "standard" volume to mass conversions for me. E.g. 1 C whole wheat flour is 5.5 oz (or 150 g).

This is walking the line of laziness (why don't I just look them up myself), but it sounds great.

Maybe I can combine the web server with a customized GNU units.

I don't love the % either.

Fun stuff, nice creation!

You can assume ingredients are mostly water and use 1kg = 1L for conversions, but a lot of ingredients violate this density assumption. You don't have to do the hard work to figure out the densities, the USDA already did it in the FoodCentral database. If you want a service that allows you create define recipes with both mass and volume indications, check out CookTime! Here's a rather complex macaron recipe from one of my friends: https://letscooktime.com/Recipes/Details?id=8a67c391-ddcc-4d...

But 1 C of flour is 120 g

*unpacked, maybe. It's about 150g packed.

But you're supposed to measure it unpacked
