How to Convert Attoliters to Microliters
To convert attoliters to microliters, multiply the volume by the following conversion ratio: 1e-12 microliters/attoliter.
Since one attoliter is equal to 1e-12 microliters, you can use this simple formula to convert:
The volume in microliters is equal to the volume in attoliters multiplied by 1e-12.
For example, here's how to convert 5 attoliters to microliters using the formula above.
How Many Microliters Are in an Attoliter?
There are 1e-12 microliters in an attoliter, which is why we use this value in the formula above.
Our attoliter to microliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Attoliters and microliters 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 Microliter?
A microliter is a unit of volume equal to 1/1,000,000 of a liter (0.000001 L). One-millionth of a liter (1 cubic millimeter). [2]
The microliter is classified as a metric and SI-compatible unit of volume. Microliters can be abbreviated as µL; for example, 1 microliter can be written as 1 µL.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microliter (µL) a convenient decimal multiple of the liter (L).
In practice, microliters (µL) 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 microliters (µL), keep full floating-point precision (1 aL = 1e-12 µL; 1 µL = 999,999,999,999.9999 aL) during intermediate calculations and round only the final microliter figure to match your instrument tolerance.
