About these units
Puncheon (pun)
84 US gallons (318 L), two tierces. A cask for rum and wine.
Richard III is named as having set the wine puncheon at 84 gallons, a size that works out to about 318 litres (317.97 L as used here) in US wine gallons, or 70 imperial gallons. Wikipedia notes the US puncheon is four thirds of a hogshead, so it also equals two tierces.
Unlike the neat wine figure, the puncheon was a loose term in practice. British usage for beer, wine and spirits placed it anywhere between 70 and 120 imperial gallons, roughly 318 to 546 litres, so a puncheon of rum could be markedly larger than one of wine. Any stated size therefore depends on the trade and the period.
Within the English wine ladder it falls between the 63 gallon hogshead and the 126 gallon butt, a third of a tun. The ratios are exact in US gallons: it equals two tierces and four thirds of a hogshead.
1 puncheon = 317.9745899 liters (approximately).

US Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
