How to Convert Femtoliters to Microliters

To convert femtoliters to microliters, multiply the volume by the following conversion ratio: 1e-9 microliters/femtoliter.

Since one femtoliter is equal to 1e-9 microliters, you can use this simple formula to convert:

microliters = femtoliters × 1e-9

The volume in microliters is equal to the volume in femtoliters multiplied by 1e-9.

For example, here's how to convert 5 femtoliters to microliters using the formula above.

microliters = (5 fL × 1e-9) = 5e-9 µL

How Many Microliters Are in a Femtoliter?

There are 1e-9 microliters in a femtoliter, which is why we use this value in the formula above.

1 fL = 1e-9 µL|1 µL = 999,999,999.9999999 fL

Our femtoliter to microliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Femtoliters and microliters are both units used to measure volume. Keep reading to learn more about each unit.

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). [1]

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.

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 femtoliters (fL) and microliters (µL), keep full floating-point precision (1 fL = 1e-9 µL; 1 µL = 999,999,999.9999999 fL) during intermediate calculations and round only the final microliter figure to match your instrument tolerance.
