US Gallons to Cubic Centimeters (gal to cm³)
1 US gallon equals 3,785.411784 cubic centimeters exactly.
How to convert US gallons to cubic centimeters
To convert US gallons to cubic centimeters, multiply the number of US gallons by 3,785.411784. This factor is exact. To go the other way, multiply cubic centimeters by 0.0002641720524 (rounded).
cubic centimeters = US gallons × 3,785.411784
Example: 10 US gallons = 37,854.11784 cubic centimeters.
Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.
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).

Cubic Centimeter (cm³)
Exactly one milliliter. Used for engine displacement (as 'cc') and in medicine.
Cubic centimeter is the volume of a cube one centimeter on each side, and it belonged to the old centimeter-gram-second system of units, in which one cubic centimeter of water was meant to weigh about one gram. Its famous abbreviation, cc, is not an SI symbol at all. The official symbol is cm³, yet cc stuck in medicine, cooking and engineering because it is quick to write and say.
A cubic centimeter equals exactly one milliliter, so the two names are interchangeable and which one you meet depends on the field. Doses are often written in cc. Motorcyclists, scooter makers and engine builders use it for displacement: the swept volume is the bore area times the stroke times the number of cylinders, so a 1,000 cc sport bike can move eight times as much air per cycle as a 125 cc scooter. One cubic inch is 16.38706 cubic centimeters, which lets Americans and Europeans compare engines.
1 cubic centimeter = 0.001 liters (exactly).
