Understanding Fluid Ounces vs Weight Ounces
It's important to distinguish between fluid ounces and weight ounces:
- Fluid ounces (fl oz): Measure volume (how much space something takes up)

For water, 1 fluid ounce weighs approximately 1 ounce. However, for other ingredients like flour, sugar, or oil, the weight and volume measurements are different. Always check whether a recipe calls for fluid ounces (volume) or ounces (weight).
