How the formula works
Both attoampere and zeptoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attoamperes by 1000 to get zeptoamperes. To reverse the conversion, multiply a zeptoampere value by 0.001 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 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 attoamperes to zeptoamperes?
Multiply the attoampere value by 1000 to get the equivalent in zeptoamperes. For example, 5 aA × 1000 = 5000 zA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert zeptoamperes back to attoamperes?
Yes. Divide the zeptoampere value by 1000, or multiply it by 0.001, to get attoamperes.
