How the formula works
Both centiampere and ampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiamperes by 0.01 to get amperes. To reverse the conversion, multiply a ampere value by 100 to get back to centiamperes.
Frequently asked questions
What is Centiampere (cA)?
A Centiampere (cA) equals 1/100 ampere(s), a scaled unit of electric current used for centi-scale electrical work.
What is Ampere (A)?
The ampere (A) is the SI unit of electric current, measuring the rate of flow of electric charge.
How do I convert centiamperes to amperes?
Multiply the centiampere value by 0.01 to get the equivalent in amperes. For example, 5 cA × 0.01 = 0.05 A.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.01 is an exact, non-rounded value.
Can I convert amperes back to centiamperes?
Yes. Divide the ampere value by 0.01, or multiply it by 100, to get centiamperes.
