About these units
US Peck (pk)
One quarter of a US bushel (8.81 L), a traditional measure for apples and other produce.
Anyone who has recited the tongue twister about Peter Piper has met the peck, a dry measure of a quarter bushel. The American version is about 8.81 L, or 8 dry quarts, and the imperial peck set after 1824 is larger at about 9.09 L. Scotland had its own pecks before that act, roughly 9 L for wheat, peas, beans and meal and about 13 L for barley, oats and malt, with four pecks making a firlot.
In Britain the peck is obsolete apart from the rhyme and a few older Bible translations, where it appears in Matthew 5:15. In the United States it lingers in grocery stores and farm stands, where apples and some other produce are still sold by the peck. NIST gives the US peck as 8.809768 L.
1 US peck = 8.809767542 liters (approximately).

US Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).
