Wineglass to Milliliter Converter

About this calculator

The wineglass is an old English cooking and pharmacy measure that predates standardized metric units, commonly found in vintage British and early American recipes and apothecary instructions. It is conventionally taken as 2 fluid ounces, equal to 60 mL, a fixed but now largely obsolete volume unit that sits between a tablespoon and a modern cup.

Because it shows up in historical recipe books and old medical dosage instructions where no modern equivalent is given, cooks and researchers restoring or adapting these recipes need to convert wineglass quantities into today’s standard milliliters (or fluid ounces) to use them with modern measuring tools. This calculator converts between wineglasses and milliliters in either direction using the 1 wineglass = 60 mL relationship.
