How the formula works
Both coulomb and decacoulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in coulombs by 0.1 to get decacoulombs. To reverse the conversion, multiply a decacoulomb value by 10 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 Decacoulomb (daC)?
A Decacoulomb (daC) equals 10 coulomb(s), a scaled unit of electric charge used for deca-scale electrical work.
How do I convert coulombs to decacoulombs?
Multiply the coulomb value by 0.1 to get the equivalent in decacoulombs. For example, 5 C × 0.1 = 0.5 daC.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.1 is an exact, non-rounded value.
Can I convert decacoulombs back to coulombs?
Yes. Divide the decacoulomb value by 0.1, or multiply it by 10, to get coulombs.
