How the formula works
Both centiampere and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiamperes by 10 to get milliamperes. To reverse the conversion, multiply a milliampere value by 0.1 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 Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert centiamperes to milliamperes?
Multiply the centiampere value by 10 to get the equivalent in milliamperes. For example, 5 cA × 10 = 50 mA.
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 milliamperes back to centiamperes?
Yes. Divide the milliampere value by 10, or multiply it by 0.1, to get centiamperes.
