Convert coulomb to ampere second

Coulomb

The coulomb (symbol: C) is the SI unit of electric charge. It is the charge transported by a constant current of one ampere in one second. One coulomb equals the charge of approximately 6.242×10¹⁸ elementary charges (electrons or protons).

Ampere-Second

The ampere-second (symbol: A·s) is equivalent to one coulomb, the SI unit of electric charge. It represents the charge transferred by a current of one ampere flowing for one second.

How to convert Coulomb to Ampere-Second

1 C = 1 A·s. To convert any value, multiply it by 1. For example, 25 C = 25 A·s.

Frequently asked questions

How many A·s are there in one C?: One C is equal to 1 A·s.
How do you convert Coulomb to Ampere-Second?: Multiply the value in Coulomb by 1 to get the result in Ampere-Second.
How much is 25 C in A·s?: 25 C is equal to 25 A·s.
How do you convert Ampere-Second back to Coulomb?: Divide by the same factor: multiply the value in Ampere-Second by 1 to get Coulomb.
