How to Convert Femtofarads to Microfarads

To convert femtofarads to microfarads, multiply the capacitance by the following conversion ratio: 1e-9 microfarads/femtofarad.

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

microfarads = femtofarads × 1e-9

The capacitance in microfarads is equal to the capacitance in femtofarads multiplied by 1e-9.

For example, here's how to convert 5 femtofarads to microfarads using the formula above.

microfarads = (5 fF × 1e-9) = 5e-9 µF

How Many Microfarads Are in a Femtofarad?

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

1 fF = 1e-9 µF|1 µF = 999,999,999.9999999 fF

Our femtofarad to microfarad calculator automatically converts your capacitance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Femtofarads and microfarads are both units used to measure capacitance. Keep reading to learn more about each unit.

What Is a Femtofarad?

A femtofarad is a unit of capacitance equal to 1e-15 farads (F), the base unit for capacitance. 10⁻¹⁵ Farads. [1]

The femtofarad is classified as a metric and SI-compatible unit of capacitance. Femtofarads can be abbreviated as fF; for example, 1 femtofarad can be written as 1 fF.

In the metric system, "femto" is the standard SI prefix for quadrillionths, or 10⁻¹⁵. This makes the femtofarad (fF) a convenient decimal multiple of the farad (F).

In practice, femtofarads (fF) are widely used across fine-tolerance laboratory, analytical, and micro-scale capacitance measurements within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Microfarad?

A microfarad is a unit of capacitance equal to 1/1,000,000 of a farad (0.000001 F). One-millionth of a Farad (10⁻⁶ F). [2]

The microfarad is classified as a metric and SI-compatible unit of capacitance. Microfarads can be abbreviated as µF; for example, 1 microfarad can be written as 1 µF.

In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microfarad (µF) a convenient decimal multiple of the farad (F).

In practice, microfarads (µF) are widely used across fine-tolerance laboratory, analytical, and micro-scale capacitance measurements within SI metric workflows, engineering documentation, and technical data sheets.

When converting capacitance between femtofarads (fF) and microfarads (µF), keep full floating-point precision (1 fF = 1e-9 µF; 1 µF = 999,999,999.9999999 fF) during intermediate calculations and round only the final microfarad figure to match your instrument tolerance.
