electron charge, e

=

coulombs, C

10 pC (read as 10 pico coulombs) = 10e-12 coulombs, C

In high voltage (115 kV as an example) transformer and circuit breakers partial discharge are measured in pico coulombs, pC. Understanding this measurement is important in reading factory test report.

ampere-hr, Ah

=

coulombs, C

1 Ampere = 1 coulomb / sec; 1 coulomb = 16 x 10¹⁸ electron charge
it means 16 quintillion of electron charge is being transported per second.
16 quintillion = 16,000,000,000,000,000,000

---

Faraday constant, F = coulombs / mol

---

gas constant , = J / (kmol*K)

---

gas constant , = kPa*m³ / (kmol*K)

---

gas constant , = ft-lbf / (lb mole - ⁰R)

---

gas constant , = L-atm / (mole-K)

---

gravity accel. , g = m / sec²

---

gravity accel. , g = ft / sec²

---

molar volume , V_m = L / kmol

---

speed of light , c = m/s

---

speed of light , c = km/s
