How the formula works
Both centiampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiamperes by 1.000000e+16 to get attoamperes. To reverse the conversion, multiply a attoampere value by 1.000000e-16 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 Attoampere (aA)?
An Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
How do I convert centiamperes to attoamperes?
Multiply the centiampere value by 1.000000e+16 to get the equivalent in attoamperes. For example, 5 cA × 1.000000e+16 = 5.000000e+16 aA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+16 is an exact, non-rounded value.
Can I convert attoamperes back to centiamperes?
Yes. Divide the attoampere value by 1.000000e+16, or multiply it by 1.000000e-16, to get centiamperes.
