Capacity measure
As a supplemental unit of apothecary measure and as a culinary measurement unit, the wine glass (also known as wineglass, wineglassful (pl. wineglassesful), or cyathus vinarius in pharmaceutical Latin) is defined as 2 US customary fluid ounces (1/8 of a US customary pint; about 2·08 British imperial fluid ounces or 59·15mL) in the US and 2 British imperial fluid ounces (1/10 of a British imperial pint; about 1·92 US customary fluid ounces or 56·83mL) in the UK. An older version (before c. 1800) was 11/2 fluid ounces. These units bear little relation to the capacity of most contemporary wineglasses (based on 1/6 bottle, or 125mL; about 4·40 British imperial fluid ounces or 4·23 US customary fluid ounces) or to the ancient Roman cyathus (about 45mL, 1·58 British imperial fluid ounces, or 1·52 US customary fluid ounces).
