How the formula works
Both picoampere and ampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picoamperes by 1.000000e-12 to get amperes. To reverse the conversion, multiply a ampere value by 1.000000e+12 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 Ampere (A)?
The ampere (A) is the SI unit of electric current, measuring the rate of flow of electric charge.
How do I convert picoamperes to amperes?
Multiply the picoampere value by 1.000000e-12 to get the equivalent in amperes. For example, 5 pA × 1.000000e-12 = 5.000000e-12 A.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert amperes back to picoamperes?
Yes. Divide the ampere value by 1.000000e-12, or multiply it by 1.000000e+12, to get picoamperes.
