About Cups
A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
About Tuns
A tun = 4 hogsheads = 252 US gallons ≈ 953.9 L - the largest traditional wine cask and origin of the English word 'ton': a full tun of wine weighed ~1 long ton. English shipping law rated cargo capacity in 'tuns burden'. Scottish distilleries use 'tun rooms' for large vatting/blending vats. 1 tun = 252 US gal = 2 pipes = 4 hogsheads ≈ 953.9 L.
