Still better than Imperial.

A peck is an imperial and United States customary unit of dry volume,[1] equivalent to 2 dry gallons or 8 dry quarts or 16 dry pints. An imperial peck is equivalent to 9.09 liters and a US customary peck is equivalent to 8.81 liters. Two pecks make a kenning (obsolete), and four pecks make a bushel. Although the peck is no longer widely used, some produce, such as apples, are still often sold by the peck in the U.S. (although it is obsolete in the UK, found only in the old nursery rhyme "Peter Piper" and in the Bible – e.g., Matthew 5:15 in some older translations).

so 8.81 liters for the rest of us. Now we just need to work out what a dry gallon is.

The dry gallon, also known as the corn gallon or grain gallon, is a historic British dry measure of volume that was used to measure grain and other dry commodities and whose earliest recorded official definition, in 1303, was the volume of 8 pounds (3.6 kg) of wheat.[1] The US fluid gallon is about 14.1% smaller than the US dry gallon, while the Imperial fluid gallon is about 3.2% larger than the US dry gallon.

No... No!

The dry gallon's implicit value in the US system was originally one eighth of the Winchester bushel, which was a cylindrical measure of 18.5 inches (469.9 mm) in diameter and 8 inches (203.2 mm) in depth, making it an irrational number of cubic inches; its value to seven significant digits was 268.8025 cubic inches (4.404884 litres), from an exact value of 9.252 × π cubic inches. Since the bushel was later redefined to be exactly 2150.42 cubic inches, 268.8025 became the exact value for the dry gallon (268.8025 cubic inches is 4.40488377086 L).
