How to Convert Microfarads to Femtofarads
To convert microfarads to femtofarads, multiply the capacitance by the following conversion ratio: 999,999,999.9999999 femtofarads/microfarad.
Since one microfarad is equal to 999,999,999.9999999 femtofarads, you can use this simple formula to convert:
The capacitance in femtofarads is equal to the capacitance in microfarads multiplied by 999,999,999.9999999.
For example, here's how to convert 5 microfarads to femtofarads using the formula above.
How Many Femtofarads Are in a Microfarad?
There are 999,999,999.9999999 femtofarads in a microfarad, which is why we use this value in the formula above.
Our microfarad to femtofarad calculator automatically converts your capacitance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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). [1]
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.
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. [2]
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.
When converting capacitance between microfarads (µF) and femtofarads (fF), keep full floating-point precision (1 µF = 999,999,999.9999999 fF; 1 fF = 1e-9 µF) during intermediate calculations and round only the final femtofarad figure to match your instrument tolerance.
