Nanocoulombs to Coulombs

The nanocoulomb and the coulomb both measure electric charge, and one nanocoulomb is one billionth of a coulomb. Enter a charge in nC and press Convert to see the same charge expressed in coulombs.

How to convert nanocoulombs to coulombs

A nanocoulomb is one billionth of a coulomb, so a reading in nC always turns into a much smaller number once it is written in C. The fixed relationship between the two units is 1 nC = 1/1000000000 C.

To change any value, take the number of nanocoulombs and divide it by 1000000000. What comes back is the same amount of electric charge, only reported in coulombs instead.

Type the charge into the field, press Convert, and the coulomb figure appears beside the C label. Copy keeps the result for later use, and Clear empties the field so you can try another value.

Nanocoulombs to coulombs formula

Q(C) = Q(nC) / 1000000000: the charge in coulombs equals the charge in nanocoulombs divided by ten to the ninth power.

For example, a charge of 3 nanocoulombs gives Q(C) = 3 nC / 1000000000 = 3 x 10^-9 C, which is the same as 0.000000003 C. Running the relationship the other way, 1 C = 1000000000 nC, so coulombs become nanocoulombs by multiplying by 1000000000.
