About Gallon (US) (gal (US))
Definition
The US gallon is a unit of volume equal to 128 US fluid ounces, or approximately 3.785 liters, used for large liquid volumes.
Mathematical Relationship
1 US gal = 4 US qt = 8 US pt = 16 US cups = 128 US fl oz = 3.785411784 L.
Conversion Formula
To liters: multiply by 3.785. To UK gallons: multiply by 0.832674. To cubic meters: multiply by 0.003785.
Practical Applications
Fuel prices ($/gal), milk jugs, water cooler bottles, swimming pool chemicals, and paint quantities.
Interesting Facts
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!
Common Mistakes
Confusing US and UK gallons — UK gallons are 20% larger. Fuel economy (mpg) differs significantly between the two systems.
Educational Tips
1 gallon ≈ 3.8 liters ≈ a large milk jug. 4 quarts = 1 gallon. A gallon of water weighs about 8.3 pounds.
About Femtoliter (fL)
Definition
The femtoliter is a unit of volume equal to 10⁻¹⁵ liters, or one quadrillionth of a liter.
Mathematical Relationship
1 fL = 10⁻¹⁵ L = 10⁻¹² mL = 1,000 aL = 1 µm³ (cubic micrometer).
Conversion Formula
To liters: multiply by 10⁻¹⁵. To picoliters: divide by 1,000. To attoliters: multiply by 1,000.
Practical Applications
Measuring red blood cell volumes (normal MCV: 80–100 fL), inkjet droplet sizes, and flow cytometry particle analysis.
Interesting Facts
A human red blood cell has a volume of about 90 fL. The smallest inkjet droplets are in the range of 1–5 fL.
Common Mistakes
Assuming fL is too small to be practical — it is actually the standard unit used on every complete blood count (CBC) lab report.
Educational Tips
Remember: fL = femtoliter, the volume of blood cells. Normal MCV range: 80–100 fL. It's a key clinical measurement.
