The US gallon is a unit of volume equal to 128 US fluid ounces, or approximately 3.785 liters, used for large liquid volumes.
1 US gal = 4 US qt = 8 US pt = 16 US cups = 128 US fl oz = 3.785411784 L.
To liters: multiply by 3.785. To UK gallons: multiply by 0.832674. To cubic meters: multiply by 0.003785.
Fuel prices ($/gal), milk jugs, water cooler bottles, swimming pool chemicals, and paint quantities.
The US gallon is smaller than the UK gallon: 3.785 L vs. 4.546 L. This means UK fuel economy figures look better by number!
Confusing US and UK gallons — UK gallons are 20% larger. Fuel economy (mpg) differs significantly between the two systems.
1 gallon ≈ 3.8 liters ≈ a large milk jug. 4 quarts = 1 gallon. A gallon of water weighs about 8.3 pounds.
The cubic millimeter is a unit of volume equal to a cube with edges of one millimeter (10⁻⁹ m³), representing one billionth of a cubic meter.
1 mm³ = 10⁻⁹ m³ = 10⁻⁶ L = 1 µL = 0.001 cm³. One cubic centimeter contains 1,000 mm³.
To liters: multiply by 10⁻⁶. To cm³: divide by 1,000. To cubic inches: multiply by 6.1024 × 10⁻⁵.
Measuring tiny liquid drops, medical micro-dosing, ink droplet volumes in inkjet printers, and micro-fluidic devices.
A single raindrop contains roughly 50,000–100,000 mm³ of water. One mm³ of blood contains about 5 million red blood cells.
Confusing mm³ with mL — there are 1,000 mm³ in 1 mL. Also, forgetting that mm³ = µL in volume equivalence.
Remember: 1 mm³ = 1 microliter. Visualize it as a tiny cube only 1 mm on each side — barely visible to the naked eye.
