How the formula works
Both coulomb and nanocoulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in coulombs by 1.000000e+09 to get nanocoulombs. To reverse the conversion, multiply a nanocoulomb value by 1.000000e-09 to get back to coulombs.
Frequently asked questions
What is Coulomb (C)?
The coulomb (C) is the SI unit of electric charge, equal to the charge carried by a steady current of one ampere flowing for one second.
What is Nanocoulomb (nC)?
A Nanocoulomb (nC) equals 1e-09 coulomb(s), a scaled unit of electric charge used for nano-scale electrical work.
How do I convert coulombs to nanocoulombs?
Multiply the coulomb value by 1.000000e+09 to get the equivalent in nanocoulombs. For example, 5 C × 1.000000e+09 = 5.000000e+09 nC.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert nanocoulombs back to coulombs?
Yes. Divide the nanocoulomb value by 1.000000e+09, or multiply it by 1.000000e-09, to get coulombs.
