About This Calculator
The Capacitance Conversion Calculator is a free online tool that lets you convert between all standard SI capacitance units: farad (F), millifarad (mF), microfarad (µF), nanofarad (nF), and picofarad (pF). Whether you are an electronics hobbyist, an electrical engineer, a physics student, or a technician working with capacitors, this converter helps you quickly translate capacitance values between different unit scales.
How Capacitance Conversion Works
Capacitance is measured in farads (F), named after the English scientist Michael Faraday. One farad is defined as the capacitance of a capacitor that stores one coulomb of charge when one volt is applied across its plates. In practice, the farad is an extremely large unit, so most capacitors are rated in much smaller units: millifarads (10⁻³ F), microfarads (10⁻⁶ F), nanofarads (10⁻⁹ F), and picofarads (10⁻¹² F).
The conversion between these units follows a simple decimal scale where each step is a factor of 1,000. For example, to convert from farads to microfarads, multiply by 1,000,000; to convert from nanofarads to picofarads, multiply by 1,000. The formula is: base value in farads = input value × conversion factor of source unit. Then target value = base value ÷ conversion factor of target unit.
Regional Notes
Capacitance units are SI units and are universally standardized across all countries, including the US, UK, India, and the rest of the world. The same conversion factors apply everywhere. Capacitor markings may differ by region (e.g., US vs European coding standards), but the underlying unit values are identical.
Frequently Asked Questions
How do I use the capacitance conversion calculator?
Enter the capacitance value, select the unit you are converting from (e.g. farads), and select the unit you want to convert to (e.g. microfarads). Click Convert to instantly see the result along with a comparison table showing the value in all supported units.
What capacitance units does this converter support?
This calculator supports all common SI capacitance units: farad (F), millifarad (mF), microfarad (µF), nanofarad (nF), and picofarad (pF).
How do I convert farads to microfarads?
To convert farads to microfarads, multiply the capacitance in farads by 1,000,000. For example, 0.00001 F × 1,000,000 = 10 µF.
How do I convert nanofarads to picofarads?
To convert nanofarads to picofarads, multiply the capacitance in nanofarads by 1,000. For example, 100 nF × 1,000 = 100,000 pF.
What is the relationship between farad, microfarad, nanofarad, and picofarad?
1 farad (F) = 1,000 millifarads (mF) = 1,000,000 microfarads (µF) = 1,000,000,000 nanofarads (nF) = 1,000,000,000,000 picofarads (pF). Each step is a factor of 1,000.
Why is the farad not commonly used in practical circuits?
The farad is a very large unit of capacitance. A 1 farad capacitor can store 1 coulomb of charge at 1 volt, which produces enormous force. Practical capacitors typically range from picofarads (pF) to millifarads (mF). Supercapacitors may reach several farads but are still rare in standard electronics.
Is capacitance conversion the same in the US, UK, and India?
Yes, capacitance units are SI units and are universally standardized. The farad (F), millifarad (mF), microfarad (µF), nanofarad (nF), and picofarad (pF) are identical worldwide, so conversion factors are the same in the US, UK, India, and all other countries.
