Nanocoulombs

A nanocoulomb (nC) is a unit of electric charge in the International System of Units (SI). It is equal to one billionth of a coulomb (C). The prefix "nano" signifies a factor of 10 to the power of negative nine (10^-9). Therefore, one nanocoulomb is equivalent to 10^-9 coulombs. The coulomb is the SI base unit of electric charge, defined as the amount of charge transported by a constant current of one ampere in one second. Nanocoulombs are often used to express very small quantities of electric charge encountered in various scientific and technological applications. For example, in semiconductor physics and electronics, charge distributions on microelectronic devices are frequently measured in nanocoulombs. Similarly, in electrostatics, the charge on small particles or the induced charge on surfaces can be on the order of nanocoulombs. The relationship between nanocoulombs and other units of charge is straightforward; 1000 nanocoulombs equal one microcoulomb (µC), and 1,000,000 nanocoulombs equal one millicoulomb (mC).
