How the formula works
Both picoampere and zeptoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picoamperes by 1.000000e+09 to get zeptoamperes. To reverse the conversion, multiply a zeptoampere value by 1.000000e-09 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 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 picoamperes to zeptoamperes?
Multiply the picoampere value by 1.000000e+09 to get the equivalent in zeptoamperes. For example, 5 pA × 1.000000e+09 = 5.000000e+09 zA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert zeptoamperes back to picoamperes?
Yes. Divide the zeptoampere value by 1.000000e+09, or multiply it by 1.000000e-09, to get picoamperes.
