dcterms:description |
The statcoulomb (\(statC\)) or franklin (\(Fr\)) or electrostatic unit of charge (\(esu\)) is the physical unit for electrical charge used in the centimetre-gram-second system of units (cgs) and Gaussian units. It is a derived unit given by \(1\ statC = 1\ g\ cm\ s = 1\ erg\ cm\). The SI system of units uses the coulomb (C) instead. The conversion between C and statC is different in different contexts. The number 2997924580 is 10 times the value of the speed of light expressed in meters/second, and the conversions are exact except where indicated. The coulomb is an extremely large charge rarely encountered in electrostatics, while the statcoulomb is closer to everyday charges. |

- \(1 C \leftrightarrow 2997924580 statC \approx 3.00 \times 10^9 statC,\ 1 \hspace{0.3pc} statC \leftrightarrow \hspace{0.3pc} \approx 3.34 \times 10^{-10} C\) for electric charge.
- \(1 C \leftrightarrow 4 \pi \times 2997924580 statC \approx 3.77 \times 10^{10} statC,\ 1 \hspace{0.3pc} statC \leftrightarrow \hspace{0.2pc} \approx 2.6 \times 10^{-11} C\) for electric flux \(\Phi_D\)
- \(1 C/m \leftrightarrow 4 \pi \times 2997924580 \times 10^{-4} statC/cm \approx 3.77 \times 10^6 statC/cm,\ 1 \hspace{0.3pc} statC/cm \leftrightarrow \hspace{0.3pc} \approx 2.65 \times 10^{-7} C/m\) for electric displacement field \(D\).
