How the formula works
Both coulomb and decicoulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in coulombs by 10 to get decicoulombs. To reverse the conversion, multiply a decicoulomb value by 0.1 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 Decicoulomb (dC)?
A Decicoulomb (dC) equals 1/10 coulomb(s), a scaled unit of electric charge used for deci-scale electrical work.
How do I convert coulombs to decicoulombs?
Multiply the coulomb value by 10 to get the equivalent in decicoulombs. For example, 5 C × 10 = 50 dC.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 10 is an exact, non-rounded value.
Can I convert decicoulombs back to coulombs?
Yes. Divide the decicoulomb value by 10, or multiply it by 0.1, to get coulombs.
