Tips & Notes
- ✓US standard drink = 1.5 fl oz (44 ml) of spirits, 5 fl oz (148 ml) wine, 12 fl oz (355 ml) beer.
- ✓A US pint = 16 fl oz = 473.2 ml. A UK pint = 20 fl oz = 568.3 ml — significantly larger.
- ✓Shot glass sizes vary: standard US shot = 1.5 fl oz = 44 ml; many bars use 1 oz = 30 ml.
- ✓For cooking: 1 fl oz = 2 tablespoons = 6 teaspoons.
Common Mistakes
- ✗Confusing US fluid oz (29.57 ml) with UK fluid oz (28.41 ml) — 4% difference.
- ✗Confusing fluid ounces (volume) with ounces by weight — 1 fl oz of water ≈ 1 oz by weight, but not for other liquids.
- ✗Assuming 1 cup = 10 fl oz (UK) — the US cup is 8 fl oz, UK cup is 10 fl oz.
- ✗Using fl oz for dry ingredients — baking flour and sugar should be measured by weight, not volume.
Fluid Ounces to Milliliters Overview
What This Calculator Does
Converts fluid ounces to and from milliliters, liters, and cups. Supports both US fl oz (29.5735 mL) and UK imperial fl oz (28.4131 mL).
US vs UK Fluid Ounces — 4% Difference
| Unit | mL | Used Where | |------|----|-----------| | 1 US fl oz | 29.5735 mL | USA, Americas | | 1 UK fl oz | 28.4131 mL | UK historical |
A 12 fl oz US can = 354.9 mL. A 12 fl oz UK measure = 340.9 mL. For recipes crossing US/UK, this matters.
Common Beverage Sizes
| Product | US fl oz | mL | |---------|----------|----| | Shot glass | 1.5 fl oz | 44.4 mL | | Standard soda can | 12 fl oz | 355 mL | | Water bottle | 16.9 fl oz | 500 mL | | Wine pour (standard) | 5 fl oz | 148 mL | | US pint | 16 fl oz | 473 mL |
Fluid Oz vs Weight Oz
Fluid ounces measure volume; weight ounces measure mass. 1 fl oz of water ≈ 1.04 oz by weight. For dense liquids (honey, oil), they diverge significantly.
