How the formula works
Both ampere and centiampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in amperes by 100 to get centiamperes. To reverse the conversion, multiply a centiampere value by 0.01 to get back to amperes.
Frequently asked questions
What is Ampere (A)?
The ampere (A) is the SI unit of electric current, measuring the rate of flow of electric charge.
What is Centiampere (cA)?
A Centiampere (cA) equals 1/100 ampere(s), a scaled unit of electric current used for centi-scale electrical work.
How do I convert amperes to centiamperes?
Multiply the ampere value by 100 to get the equivalent in centiamperes. For example, 5 A × 100 = 500 cA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 100 is an exact, non-rounded value.
Can I convert centiamperes back to amperes?
Yes. Divide the centiampere value by 100, or multiply it by 0.01, to get amperes.
