About these units

Milliliter (mL)

Metric (SI)Current unit

One thousandth of a liter, or exactly 1 cubic centimeter. Used for medicine, cooking and small containers.

Milliliters inherit everything from the liter, since the prefix simply means one thousandth. Because the liter is a cubic decimeter, a milliliter works out to exactly one cubic centimeter, a coincidence the metric system built in on purpose so that volume, length and mass interlock. One milliliter of water has a mass of about one gram, so a dosing syringe, a kitchen scale and a measuring jug can all be checked against one another.

Today milliliters dominate wherever small amounts must be measured precisely: medicine, flavorings, perfume, shampoo and the fine print on drink labels. Spelling is a mild regional split, with uppercase mL preferred in the United States, Canada and Australia and lowercase ml common in the UK and Europe. For scale, a US teaspoon is just under 5 mL, a US tablespoon is about 14.8 mL, and the US nutrition-label cup is exactly 240 mL, so one such cup is 240 of these tiny units.

1 milliliter = 0.001 liters (exactly).

Puncheon (pun)

US customaryHistorical unit (no longer in standard use)

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).
