Use YUGUANG’s Capacitance Conversion Chart and Calculator to easily convert capacitor codes to actual capacitance values and perform unit conversions between picofarads (pF), nanofarads (nF), microfarads (µF), and farads (F). This tool helps engineers and hobbyists quickly interpret capacitor markings and compare capacitance values across different unit systems.
Enter your parameters below to calculate results.
Capacitors are fundamental electronic components, but their values can be confusing because different manufacturers and regions use different multipliers. Values are typically expressed in Microfarads (F), Nanofarads (nF), or Picofarads (pF).
There is often overlap between these multipliers. For example, a capacitor might be listed as 0.1 F on a schematic, but the physical part you buy might be marked as 100 nF. These represent the exact same capacitance value.

Note: The usage of Nanofarads (nF) varies by region. In some areas, it is common to skip nF entirely, expressing values only as fractions of a Microfarad (e.g., ) or large multiples of Picofarads.
Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge.
The Formula:
The relationship between capacitance (), charge (), and voltage () is defined as:
Where:
While the standard unit is the Farad (F), a single Farad is an extremely large amount of capacitance. In practical electronics, we almost always use prefixes to denote smaller values:
Use the table below to quickly convert between the three most common multipliers.
