An imperial fluid ounce is 1⁄20 of an imperial pint, 1⁄160 of an imperial gallon or exactly 28.4130625 mL.
A US customary fluid ounce is 1⁄16 of a US liquid pint and 1⁄128 of a US liquid gallon or exactly 29.5735295625 mL, making it about 4.08% larger than the imperial fluid ounce.
A US food labeling fluid ounce is exactly 30 mL.
So we have 28.4g, 29.6g or 30g of water. An ounce is 28.3g (closest to the imperial measures and neither of the US ones, despite the ounce being common to imperial and US systems)
I’d consider that within the margin of error for a volumetric measurement. Especially if you are being lazy like me and measuring something like milk by weight.
Funny enough, you made me go check my kitchen scales. They report in grams, ounces, and weirdly milliliters and fluid ounces. I used my scale that reports in hundredths of a gram to measure out exactly 1 oz mass. I then placed it on my other three scales to see what it would read. 2 of them correctly reported that they weren’t quite at 1 fluid ounce, while the other said it was. I never actually put my scales in ounce mode, though.
It does, but I would still rather use grams usually. My ice cream base recipe says 500g skim milk and 470g heavy cream. I don’t have to get a measuring cup dirty—I just pour them into the bowl.
The only thing that really matters is the average milk fat %. I like Costco’s 40% heavy cream from a price and quality standpoint. My family drinks skim milk. If I mix those two equally I will end up with about 20% fat which makes a very nice ice cream.
Use non-American recipes.
The rest of the world does this. And guess what, 1 milliliter of water is exactly 1 gram, unlike stupid ounces.
If I want a recipe in English I always end the search query with “UK” to make sure it’s in weight, not cups. I’m not a fucking toddler
I try that too for English recipes but then I get things in tablespoons, teaspoons, pinches, good pinches, full pinches, and small bunches.
Or my favorite “a good knob of butter”
At least they aren’t using stone for flour though lol.
A fluid ounce of water is an ounce of weight
Except that’s not true.

one fluid ounce of water is one (weight) ounce of water
Not exactly true. See other comments.
Density differs for other ingredients though.

Wait, why on earth would you use skim milk in ice cream when you’re adding in basically equal parts cream anyway?

Yeah I guess if you already have skim milk around the house then that makes sense.
1 mL water is 1 gram
Hah, that was a temporary edit to mess with the other commenter 😉 Good timing for you I guess.
