How the formula works
Both picoampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picoamperes by 1000000 to get attoamperes. To reverse the conversion, multiply a attoampere value by 0.000001 to get back to picoamperes.
Frequently asked questions
What is Picoampere (pA)?
A Picoampere (pA) equals 1e-12 ampere(s), a scaled unit of electric current used for pico-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 picoamperes to attoamperes?
Multiply the picoampere value by 1000000 to get the equivalent in attoamperes. For example, 5 pA × 1000000 = 5.000000e+06 aA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000000 is an exact, non-rounded value.
Can I convert attoamperes back to picoamperes?
Yes. Divide the attoampere value by 1000000, or multiply it by 0.000001, to get picoamperes.
