About these units
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).

Jigger (jigger)
1.5 US fluid ounces (44.36 mL). A bar measure for spirits; sizes vary.
As a bartending term, jigger appeared in the United States in the early nineteenth century for a small measure of spirits or wine. A double-ended stainless steel jigger was patented in 1893 by Cornelius Dungan of Chicago. Wikipedia reports that before Prohibition an American jigger was about 2 US fluid ounces, or 59 mL, and that since the late twentieth century it has usually meant 1.5 US fluid ounces, about 44 mL.
Sizes differ by country and by habit. Wikipedia gives single measures of 30 to 44 mL in the United States, 30 mL in Australia, and 25 or 35 mL in the United Kingdom. No official single-shot size exists in the United States except in Utah, where a shot is legally 1.5 US fluid ounces. The figure used here is that modern American 1.5 US fluid ounces, 44.36 mL. A jigger is not part of SI or any national measures law, and NIST lists no jigger.
1 jigger = 0.04436029434 liters (approximately).
