How to Convert Attoliters to Femtoliters
To convert attoliters to femtoliters, multiply the volume by the following conversion ratio: 0.001 femtoliters/attoliter.
Since one attoliter is equal to 0.001 femtoliters, you can use this simple formula to convert:
The volume in femtoliters is equal to the volume in attoliters multiplied by 0.001.
For example, here's how to convert 5 attoliters to femtoliters using the formula above.
How Many Femtoliters Are in an Attoliter?
There are 0.001 femtoliters in an attoliter, which is why we use this value in the formula above.
Our attoliter to femtoliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Attoliters and femtoliters are both units used to measure volume. Keep reading to learn more about each unit.
What Is an Attoliter?
An attoliter is a unit of volume equal to 1/999,999,999,999,999,900 of a liter (1e-18 L). 10⁻¹⁸ liters. [1]
The attoliter is classified as a metric and SI-compatible unit of volume. Attoliters can be abbreviated as aL; for example, 1 attoliter can be written as 1 aL.
When working with attoliters (aL) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, attoliters (aL) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within SI metric 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 attoliters (aL) and femtoliters (fL), keep full floating-point precision (1 aL = 0.001 fL; 1 fL = 1,000 aL) during intermediate calculations and round only the final femtoliter figure to match your instrument tolerance.
