Bottle formats & portions

• 1 L = 100 cL = 1,000 mL; 1 cL = 10 mL.
• A 75 cL bottle contains 750 mL; a 37.5 cL half-bottle, 375 mL; a 1.5 L magnum, 1,500 mL.

• You may also encounter 50 cL and formats of 3 L or more.
• Always read capacity: a large-format name can vary by region.

• A US fl oz is about 29.57 mL; an imperial fl oz about 28.41 mL.
• Thus 750 mL is about 25.36 US fl oz or 26.40 imperial fl oz.

Oz alone is ambiguous

• ask whether it means fluid ounces and which system.
• An ounce of mass cannot directly calculate the number of glasses.
