How the formula works
Both ronnacoulomb and coulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnacoulombs by 1.000000e+27 to get coulombs. To reverse the conversion, multiply a coulomb value by 1.000000e-27 to get back to ronnacoulombs.
Frequently asked questions
What is Ronnacoulomb (RC)?
A Ronnacoulomb (RC) equals 1e+27 coulomb(s), a scaled unit of electric charge used for ronna-scale electrical work.
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.
How do I convert ronnacoulombs to coulombs?
Multiply the ronnacoulomb value by 1.000000e+27 to get the equivalent in coulombs. For example, 5 RC × 1.000000e+27 = 5.000000e+27 C.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+27 is an exact, non-rounded value.
Can I convert coulombs back to ronnacoulombs?
Yes. Divide the coulomb value by 1.000000e+27, or multiply it by 1.000000e-27, to get ronnacoulombs.
