How to Convert Femtofarads to Millifarads
To convert femtofarads to millifarads, multiply the capacitance by the following conversion ratio: 1e-12 millifarads/femtofarad.
Since one femtofarad is equal to 1e-12 millifarads, you can use this simple formula to convert:
The capacitance in millifarads is equal to the capacitance in femtofarads multiplied by 1e-12.
For example, here's how to convert 5 femtofarads to millifarads using the formula above.
How Many Millifarads Are in a Femtofarad?
There are 1e-12 millifarads in a femtofarad, which is why we use this value in the formula above.
Our femtofarad to millifarad calculator automatically converts your capacitance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Femtofarads and millifarads 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 Millifarad?
A millifarad is a unit of capacitance equal to 1/1,000 of a farad (0.001 F). One-thousandth of a Farad. [2]
The millifarad is classified as a metric and SI-compatible unit of capacitance. Millifarads can be abbreviated as mF; for example, 1 millifarad can be written as 1 mF.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millifarad (mF) a convenient decimal multiple of the farad (F).
In practice, millifarads (mF) 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 millifarads (mF), keep full floating-point precision (1 fF = 1e-12 mF; 1 mF = 1e+12 fF) during intermediate calculations and round only the final millifarad figure to match your instrument tolerance.
