How the formula works
Both attoampere and kiloampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attoamperes by 1.000000e-21 to get kiloamperes. To reverse the conversion, multiply a kiloampere value by 1.000000e+21 to get back to attoamperes.
Frequently asked questions
What is Attoampere (aA)?
An Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
What is Kiloampere (kA)?
A Kiloampere (kA) equals 1,000 ampere(s), a scaled unit of electric current used for kilo-scale electrical work.
How do I convert attoamperes to kiloamperes?
Multiply the attoampere value by 1.000000e-21 to get the equivalent in kiloamperes. For example, 5 aA × 1.000000e-21 = 5.000000e-21 kA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert kiloamperes back to attoamperes?
Yes. Divide the kiloampere value by 1.000000e-21, or multiply it by 1.000000e+21, to get attoamperes.
