How the formula works
Both ampere and picoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in amperes by 1.000000e+12 to get picoamperes. To reverse the conversion, multiply a picoampere value by 1.000000e-12 to get back to amperes.
Frequently asked questions
What is Ampere (A)?
The ampere (A) is the SI unit of electric current, measuring the rate of flow of electric charge.
What is Picoampere (pA)?
A Picoampere (pA) equals 1e-12 ampere(s), a scaled unit of electric current used for pico-scale electrical work.
How do I convert amperes to picoamperes?
Multiply the ampere value by 1.000000e+12 to get the equivalent in picoamperes. For example, 5 A × 1.000000e+12 = 5.000000e+12 pA.
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 picoamperes back to amperes?
Yes. Divide the picoampere value by 1.000000e+12, or multiply it by 1.000000e-12, to get amperes.
