The farad (F) is the SI unit of electrical capacitance, named after English scientist Michael Faraday. One farad is defined as the capacitance that stores one coulomb of charge when one volt is applied across it. A farad is an extremely large unit of capacitance; most practical capacitors are measured in microfarads, nanofarads, or picofarads. Supercapacitors and ultracapacitors are among the few devices with farad-level capacitance.
A microfarad (µF) is one-millionth of a farad. The prefix "micro" represents a factor of 0.000001 in the metric system. Microfarads are the most commonly used unit for capacitors in everyday electronics, including power supplies, motor start capacitors, audio circuits, and coupling/decoupling applications. Microfarad-range capacitors provide practical energy storage without excessive physical size, making them ideal for most electronic applications.
Converting farads to microfarads requires multiplication:
Example: 0.000047 F × 1,000,000 = 47 µF
There are 1,000,000 (one million) microfarads in one farad. The prefix "micro" means one-millionth, so to convert from farads to microfarads, you multiply by 1,000,000. This is why practical capacitors are usually rated in microfarads rather than farads.
The farad is an extremely large unit. A 1-farad capacitor would be impractically large for most applications. By using microfarads (µF), nanofarads (nF), or picofarads (pF), we can describe common capacitor values with convenient numbers. For example, saying "47 µF" is much more practical than "0.000047 F".
100 microfarads equals 0.0001 farads (or 1×10⁻⁴ F). To convert, divide 100 by 1,000,000. A 100 µF capacitor is a common value used in power supply filtering and audio applications, providing substantial energy storage in a compact package.
Yes, supercapacitors (also called ultracapacitors) are available with capacitance values of 1 farad or more, reaching hundreds or even thousands of farads. These devices are used for energy storage in applications like backup power systems, regenerative braking, and burst-power delivery, but they operate at relatively low voltages (2.7V to 3V typical).
Capacitors may be marked in several ways: directly as "47µF" or "47uF", as a three-digit code like "476" (47×10⁶ pF = 47 µF), or sometimes just the numeric value. Electrolytic capacitors typically show the value and voltage rating printed directly on the body. Always verify polarity for polarized capacitors.
µF (microfarad) equals 10⁻⁶ farads, while mF (millifarad) equals 10⁻³ farads. One millifarad equals 1,000 microfarads. The term "mF" is rarely used in electronics to avoid confusion. Instead, the industry uses microfarads (µF), nanofarads (nF), and picofarads (pF) as standard units.
