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)
  • Ounces (oz): Measure weight (how heavy something is)

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).

Quick Reference

  • 2 tablespoons = 1 fluid ounce
  • 8 fluid ounces = 1 cup
  • 16 fluid ounces = 1 pint
  • 32 fluid ounces = 1 quart
