FAQ

Weight is more accurate for baking. A cup of flour can vary by 20-30% depending on how it's scooped. Weighing in grams gives consistent, reproducible results - this is why professional recipes list weights.

Fluid ounces (fl oz) measure volume - this converter uses weight ounces (oz). For water, 1 fl oz ≈ 1 oz by weight. For other ingredients they differ: 1 fl oz of honey weighs about 1.5 oz because honey is denser than water.
