1 fl oz = 29.57353 ml

Example: 1 US fluid ounce = 29.57353 milliliter

A fluid ounce measures volume, not weight. The US fl oz is about 29.57 ml and the imperial fl oz about 28.41 ml, and neither matches the weight ounce (28.35 g) except roughly for water. Measure liquids in milliliters to avoid the ambiguity.
The US recipe cup is about 237 ml, neither 250 ml nor 200 ml. Rounding up to 250 ml makes a batch about 6% too big; rounding down to 200 ml about 15% too small. Use 2.4 dl per cup, or the exact 236.6 ml when baking demands precision.
