How to Convert Liters to Attoliters
To convert liters to attoliters, multiply the volume by the following conversion ratio: 1e+18 attoliters/liter.
Since one liter is equal to 1e+18 attoliters, you can use this simple formula to convert:
The volume in attoliters is equal to the volume in liters multiplied by 1e+18.
For example, here's how to convert 5 liters to attoliters using the formula above.
How Many Attoliters Are in a Liter?
There are 1e+18 attoliters in a liter, which is why we use this value in the formula above.
Our liter to attoliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Liters and attoliters are both units used to measure volume. Keep reading to learn more about each unit.
What Is a Liter?
Metric unit of volume equal to 1 cubic decimeter (1,000 mL). It serves as a primary reference unit for measuring volume across scientific and practical applications. [1]
The liter is classified as a metric and SI-compatible unit of volume. Liters can be abbreviated as L; for example, 1 liter can be written as 1 L.
As the primary coherent reference unit for volume in this category, all other volume units are mathematically anchored to the liter (L).
In practice, liters (L) are widely used across standard volume applications within SI metric workflows, engineering documentation, and technical data sheets.
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. [2]
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.
When converting volume between liters (L) and attoliters (aL), keep full floating-point precision (1 L = 1e+18 aL; 1 aL = 1e-18 L) during intermediate calculations and round only the final attoliter figure to match your instrument tolerance.
