How the formula works
Both milliampere and centiampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliamperes by 0.1 to get centiamperes. To reverse the conversion, multiply a centiampere value by 10 to get back to milliamperes.
Frequently asked questions
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.
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 milliamperes to centiamperes?
Multiply the milliampere value by 0.1 to get the equivalent in centiamperes. For example, 5 mA × 0.1 = 0.5 cA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.1 is an exact, non-rounded value.
Can I convert centiamperes back to milliamperes?
Yes. Divide the centiampere value by 0.1, or multiply it by 10, to get milliamperes.
