A hogshead (abbreviated "Hhd", plural "Hhds") is a large cask of liquid (or, less often, of a food commodity). More specifically, it refers to a specified volume, measured in either imperial or US customary measures, primarily applied to alcoholic beverages, such as wine, ale, or cider.
Canada now usually employs the metric cup of 250 mL but its conventional cup was somewhat smaller than both American and imperial units.
1 Canadian cup = 8 imperial fluid ounce = 1/20 imperial gallon = 227.3045 millilitres
1 tablespoon = 1/2 imperial fluid ounce
1 teaspoon = 1/6 imperial fluid ounce
