How to Convert Gallons to Femtoliters
To convert gallons to femtoliters, multiply the volume by the following conversion ratio: 4.54609e+15 femtoliters/gallon.
Since one gallon is equal to 4.54609e+15 femtoliters, you can use this simple formula to convert:
The volume in femtoliters is equal to the volume in gallons multiplied by 4.54609e+15.
For example, here's how to convert 5 gallons to femtoliters using the formula above.
How Many Femtoliters Are in a Gallon?
There are 4.54609e+15 femtoliters in a gallon, which is why we use this value in the formula above.
Our gallon to femtoliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Gallons and femtoliters are both units used to measure volume. Keep reading to learn more about each unit.
What Is a Gallon?
A gallon is a unit of volume equal to 4.54609 liters (L), the base unit for volume. British Imperial gallon defined as exactly 4.54609 liters. [1]
The gallon is classified as a US customary and imperial unit of volume. Gallons can be abbreviated as gal (UK); for example, 1 gallon can be written as 1 gal (UK).
When working with gallons (gal (UK)) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gallons (gal (UK)) are widely used across standard volume applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Femtoliter?
A femtoliter is a unit of volume equal to 1e-15 liters (L), the base unit for volume. 10⁻¹⁵ liters (1 µm³), used in hematology (mean corpuscular volume). [2]
The femtoliter is classified as a metric and SI-compatible unit of volume. Femtoliters can be abbreviated as fL; for example, 1 femtoliter can be written as 1 fL.
In the metric system, "femto" is the standard SI prefix for quadrillionths, or 10⁻¹⁵. This makes the femtoliter (fL) a convenient decimal multiple of the liter (L).
In practice, femtoliters (fL) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between gallons (gal (UK)) and femtoliters (fL), keep full floating-point precision (1 gal (UK) = 4.54609e+15 fL; 1 fL = 2.199692e-16 gal (UK)) during intermediate calculations and round only the final femtoliter figure to match your instrument tolerance.
