Convert Gigaampere to Picoampere
Type the number of gigaamperes that you wish to convert to picoamperes.
How to Convert Gigaamperes to Picoamperes
The gigaampere and picoampere are both units of electric current. By definition, 1 gigaampere equals exactly 1e21 picoamperes. This means to convert gigaamperes to picoamperes, you multiply by 1e21.
Formula
Step-by-Step Example
Convert 5 GA to picoamperes:
We need to convert gigaamperes to picoamperes
Since 1 GA = 1e21 pA, multiply by 1e21
5 × 1e21 = 5e21
5 GA = 5e21 pA

About These Units
Gigaampere (GA)
A gigaampere (GA) equals 10⁹ amperes. Observed only in extreme astrophysical phenomena: neutron star magnetospheres, solar flares, and relativistic jets from black holes. Earth's core generates currents estimated in the gigaampere range.
Picoampere (pA)
A picoampere (pA) equals 10⁻¹² amperes. Used in patch clamp electrophysiology measuring ion channel currents (1-100 pA), electrochemistry, radiation detectors, and precision instrumentation. Single ion channels conduct about 1-10 pA.
