Coulombs (C) and nanocoulombs (nC) are units of electric charge, which measure the amount of electric charge carried by a particle or object.
The coulomb is the SI (International System of Units) unit of electric charge. One coulomb is defined as the amount of electric charge that flows through a conductor when a current of one ampere (1 A) flows for one second (1 s). In equation form, 1 coulomb = 1 ampere × 1 second.
The prefix “nano” means one billionth (1/1,000,000,000) of a unit. Therefore, a nanocoulomb is equal to one billionth of a coulomb. It’s often used to describe small amounts of electric charge, especially in situations where larger units like coulombs are not practical due to the small scale of the charge involved.
1C = 109nC
or
1nC = 10-9C
Q(nC) = Q(C) × 109
Example – Convert 3 coulombs to nanocoulombs
Ans. Q(nC) = 3C × 109 = 3 x 109nC
| Charge (coulomb) | Charge (nanocoulomb) |
| 0 C | 0 nC |
| 0.000001 C | 103 nC |
| 0.00001 C | 104 nC |
| 0.0001 C | 105 nC |
| 0.001 C | 106 nC |
| 0.01 C | 107 nC |
| 0.1 C | 108 nC |
| 1 C | 109 nC |
1 nanocoulomb (nC) is equal to 1 × 10^-9 coulombs (C).
1 nanocoulomb (nC) is a unit of electric charge, specifically one billionth of a coulomb (C).
The unit of charge nC stands for nanocoulombs, which is a subunit of the coulomb (C).
50 nanocoulombs (nC) represent a quantity of electric charge equal to 50 billionths of a coulomb.
To convert from coulombs (C) to microcoulombs (µC), multiply the value in coulombs by 1,000,000 (10^6) since 1 µC is equal to 1 × 10^-6 C.
The number of electrons in 1 nanocoulomb (nC) depends on the context. In general, for a charge of 1 nC, there are approximately 6.242 × 10^9 electrons.
For 1 coulomb (C) of charge, there are approximately 6.242 × 10^18 electrons.
1 coulomb (C) of charge contains approximately 6.242 × 10^18 electrons.
For a charge of 9 nanocoulombs (9 nC), there are approximately 5.618 × 10^10 electrons.
