One cup, side by side
Why not use King Arthur's figure for whole milk?
Because King Arthur lists whole milk at 227 g per cup — the same number its chart gives heavy cream, yogurt, sour cream, water and vegetable oil alike. That is the eight-fluid-ounce ≈ eight-ounce baking shorthand, not a measurement; those six liquids do not all weigh the same. dishscale uses USDA FoodData Central instead, which puts whole milk at 244 g per cup. The tell that the shorthand is a shorthand is that King Arthur does not apply it to honey or maple syrup, and for both of those its figure lands within 0.1% of true density times 236.588 ml.

Is that ounces by weight, or fluid ounces?
By weight. dishscale's ounce is the international avoirdupois ounce, 28.3495 g, so one cup of Whole milk is 8.61 oz. A US fluid ounce is a volume and there are eight of them to the cup, so that same cup is 8 fl oz at the same time.
