FAQ
How do I convert US cups to ounces?
Pick the substance first, then apply its density: mass = volume × density, or volume = mass ÷ density for the reverse direction. This calculator runs both steps — density and unit conversion — in one go.
Why does the answer change when I pick a different substance?
Because US cups measures volume while ounces measures weight, and every substance packs a different mass into the same space. One US cup of water weighs about 236.6 g, while a cup of spooned flour is closer to 125 g.
How accurate are the density values?
Densities are typical room-temperature (~20 °C) values; dry goods use common spooned-in packing. Real products vary a few percent with brand, humidity, and temperature — plenty accurate for cooking and estimates, not for custody transfer.
