When you need fluid ounces to mL
Cocktail recipes are the classic case: a standard 1.5 oz jigger is about 44 mL, and a 2 oz pour is about 59 mL. Skincare and drink sizes follow the same math — a 4 oz lotion bottle is about 118 mL, and a 12 oz soda is about 355 mL.
The US customary cup is 8 fl oz, which converts to about 236.6 mL; metric recipes usually round that to 240 mL or simply use 250 mL. If precision matters in baking, weigh ingredients in grams instead.
