I memorize because of diabetes. You need to know how much sugar you eat so you do volume -> weight * carbs/weight * portion size to calculate how much insulin you are supposed to give for a meal. That is not because of cooking and having tried doing that with voice assistant several times I know it is hard to get correct numbers.
The only thing I'm reasonably sure of is that there are four quarts in a gallon - and yet, I would only bet $10 on that, not $20.
You mess up a single conversion and your finished baked goods go straight in the trash.
Weight to volume conversions are rare here but sure I do those on the fly so I guess it makes sense, do you really do you guys really do it that often? If you do extensive conversions of recipes you will need to get the ratios correct as well it is just not something I see myself doing with a voice assistant.
What do you mean it has never worked? What do you ask your assistant, and what does it respond?
> Seems like pretty hard things to do on the fly with recipes.
What's hard? I don't understand. If you need a quantity in unit x, but you only have a measuring cup or spoon in unit y, then you ask for the conversion and then you measure out that amount in unit y.
I genuinely don't understand the difficulties you seem to be encountering.
> do you really do you guys really do it that often?
Yes, literally all the time.
As things stand, I walk over to the conversion chart hanging on the fridge.
And since that stuff isn't metric, orders-of-magnitude conversions (e.g. scaling a recipe up/down) become needlessly more complex as well.
American or old British recipes; ours are all metric now.
The exception is perhaps teaspoons/tablespoons, but those are trivial metric values (5ml and 15ml), so easy enough to scale and convert if you don't have the right measuring spoon handy.
