How the formula works
Both centiampere and zeptoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centiamperes by 1.000000e+19 to get zeptoamperes. To reverse the conversion, multiply a zeptoampere value by 1.000000e-19 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 Zeptoampere (zA)?
A Zeptoampere (zA) equals 1e-21 ampere(s), a scaled unit of electric current used for zepto-scale electrical work.
How do I convert centiamperes to zeptoamperes?
Multiply the centiampere value by 1.000000e+19 to get the equivalent in zeptoamperes. For example, 5 cA × 1.000000e+19 = 5.000000e+19 zA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+19 is an exact, non-rounded value.
Can I convert zeptoamperes back to centiamperes?
Yes. Divide the zeptoampere value by 1.000000e+19, or multiply it by 1.000000e-19, to get centiamperes.
