This article will show how to convert capacitance measurement units from microfarads (µF) to millifarads (mF). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Farad, Microfarad, and Millifarad
Let’s get started by understanding the key definitions of Farad (F), Microfarad (µF), and Millifarad (mF). Understanding these terms will allow you to perform conversions confidently.
What is a Farad?
A farad (1F) is the SI base unit of electrical capacitance representing the capacity to store one coulomb (1C) of electric charge when a potential difference of one volt (1V) is applied.[1]
According to SI prefixes[2], which are based on powers of 10, a farad (1 F) is equivalent to one thousand millifarads (1,000 mF) or one million microfarads (1,000,000 µF).
What is a Microfarad (µF)?
A microfarad (µF) is a unit of electrical capacitance in the SI system equal to one millionth (1/1,000,000) of a farad (0.000001 F). It is widely used in electronics, especially for capacitors in audio circuits, filters, and timing applications.
What is a Millifarad (mF)?
A millifarad (mF) is a unit of electrical capacitance in the SI system equal to one thousandth (1/1,000) of a farad (0.001 F). It is commonly used in audio circuits, power filtering, and general-purpose electronics where moderate capacitance values are needed.
µF to mF formula
Let’s take a closer look at the conversion formula so you can carry out these conversions independently, whether using a calculator or doing it manually with pencil and paper.
The micro- prefix in the International System of Units (SI) corresponds to a multiplier of 10-6 (0.000001) while the milli- prefix represents 10-3 (0.001).
To convert microfarads (µF) to millifarads (mF), divide the capacitance value in microfarads by 1,000, since 1 millifarads equals 1,000 microfarads.
C(mF) = C(µF) ÷ 1,000
Or remember the µF-to-mF conversion factor: 1 µF = 0.001 mF

Examples
Now, let's look at an example that illustrates the calculations required to convert from microfarads to millifarads (µF to mF).
Example: Supercapacitor in Renewable Energy Storage
Suppose you're designing a solar-powered backup system, and your component supplier lists a capacitor rated at 2,200 µF. The schematic, however, specifies capacitance in millifarads. You need to convert the value to ensure compatibility.
Solution
Since 1 millifarad (mF) = 103 = 1,000 microfarads (µF), we can convert 2,200 µF to millifarads by using the following formula:
Therefore, the 2,200 µF electrical capacitance is equivalent to 2.2 mF.
To solve the problem with our calculator, follow the steps below:
- Enter the value in microfarads: For this example, enter
2200into theFrombox. - View the result: The converter instantly calculates and displays the equivalent value in millifarads:
2.2 mF.
FAQs
Is a microfarad or a millifarad larger?
A millifarad (mF) is a thousand times bigger than a microfarad (µF). Here are the relationships between the units:
1 mF = 103 = 1,000 µF1 µF = 10-3 = 1 ÷ 1,000 = 0.001 mF
How to convert from microfarads to millifarads?
To convert electrical capacitance from microfarads (µF) to millifarads (mF), follow these simple steps:
- Write down the capacitance value in microfarads (µF).
- Devide it by 1,000.
- The result is the capacitance in millifarads (mF).
Why do I need to convert microfarads to millifarads?
Converting microfarads (µF) to millifarads (mF) is important because different contexts in electronics use different unit scales, and keeping them consistent avoids errors in design, simulation, and documentation.
You now know how to convert electrical capacitance from microfarads (µF) to millifarads (mF). You can quickly use our calculator to convert between the electrical capacitance measurement units to save time for future calculations.
