Electrostatic Capacitance (also known as Electric Charge Storage Capacity, Electrostatic Potential Ratio, Dielectric Charge Accumulation Ability, or Electrical Energy Storage Metric, symbolized by C) measures the quantitative ratio of change in stored electric charge (Q) to the corresponding change in electric potential difference (V) across a pair of insulated conductors or dielectric plates (C = Q ÷ V = ε0 · εr · (A ÷ d) = 2W ÷ V2, where Q is electric charge in coulombs, V is potential in volts, ε0 is vacuum permittivity, εr is dielectric constant, A is plate area, d is gap distance, and W is stored energy in joules).

Step-by-Step PCB Decoupling & EV Supercapacitor Calculation Example
To calculate the electrostatic capacitance (C) of a PCB high-speed IC power rail decoupling capacitor measuring 0.10 Microfarads (C = 0.10 μF), and calculate the capacitance of an Electric Vehicle regenerative braking supercapacitor module rated at 3,000 Farads (C = 3,000 F = 3.0 kF) into Farads (F), Nanofarads (nF), Picofarads (pF), and Statfarads (stF):
Step 1 (PCB Decoupling Capacitance in Farads): C = 0.10 μF × 1.0 × 10-6 = 0.00000010 Farads (1.0 × 10-7 F)
Step 2 (PCB Decoupling Nanofarads & Picofarads): C = 0.10 μF × 1,000 = 100.0 Nanofarads (100.0 nF) = 100,000.0 Picofarads (100,000.0 pF)
Step 3 (EV Supercapacitor Microfarads Calculation): C = 3,000 F × 1,000,000 = 3,000,000,000 Microfarads (3.0 × 109 μF)
Step 4 (EV Supercapacitor Statfarads Conversion): C = 3,000 F × 8.98755179 × 1011 = 2.696265 × 1015 Statfarads (2.696 × 1015 stF)
Thus, the PCB decoupling capacitor carries a value of 0.10 μF (100 nF = 100,000 pF), while the EV supercapacitor module stores a massive 3,000 F (3.0 kF = 3.0 × 109 μF).

History & Physics: 1745 Leyden Jar vs 1831 Michael Faraday Law (C = ε · A ÷ d)
1745 Ewald von Kleist, Musschenbroek & The Leyden Jar
In 1745 and 1746, German cleric Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek independently invented the Leyden Jar, a glass jar coated inside and out with metal foil. As the world’s first electrostatic capacitor, the Leyden Jar allowed early experimenters to store high-voltage static charge for the first time in human history.
1831 Michael Faraday & Parallel-Plate Capacitance Law (C = ε0 · εr · A ÷ d)
Named in honor of British scientist Michael Faraday, the Farad (F) was officially adopted by the International Electrical Congress in 1881. Faraday formulated the electrostatic parallel-plate capacitance law: C = ε0 · εr · (A ÷ d) (where ε0 = 8.854187 × 10-12 F/m is vacuum permittivity, εr is dielectric constant, A is plate area, and d is separation gap). This formula explains why narrowing the dielectric layer d (as in EV supercapacitors) yields thousands of Farads in a small volume.

How do you convert Microfarads (μF) to Nanofarads (nF)?
To convert Microfarads to Nanofarads, multiply μF by 1,000. For example, 0.10 μF × 1,000 = 100.0 Nanofarads (100.0 nF).

1 Statfarad (stF), also known as 1 ESU of capacitance in the CGS electrostatic system, equals exactly 1.11265 picofarads (1.11265 pF), representing the self-capacitance of a conductive sphere with a 1 cm radius in a vacuum.
