How the formula works
Both coulomb and gigacoulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in coulombs by 1.000000e-09 to get gigacoulombs. To reverse the conversion, multiply a gigacoulomb 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 Gigacoulomb (GC)?
A Gigacoulomb (GC) equals 1e+9 coulomb(s), a scaled unit of electric charge used for giga-scale electrical work.
How do I convert coulombs to gigacoulombs?
Multiply the coulomb value by 1.000000e-09 to get the equivalent in gigacoulombs. For example, 5 C × 1.000000e-09 = 5.000000e-09 GC.
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 gigacoulombs back to coulombs?
Yes. Divide the gigacoulomb value by 1.000000e-09, or multiply it by 1.000000e+09, to get coulombs.
