How the formula works
Both petaampere and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petaamperes by 1.000000e+18 to get milliamperes. To reverse the conversion, multiply a milliampere value by 1.000000e-18 to get back to petaamperes.
Frequently asked questions
What is Petaampere (PA)?
A Petaampere (PA) equals 1e+15 ampere(s), a scaled unit of electric current used for peta-scale electrical work.
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert petaamperes to milliamperes?
Multiply the petaampere value by 1.000000e+18 to get the equivalent in milliamperes. For example, 5 PA × 1.000000e+18 = 5.000000e+18 mA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+18 is an exact, non-rounded value.
Can I convert milliamperes back to petaamperes?
Yes. Divide the milliampere value by 1.000000e+18, or multiply it by 1.000000e-18, to get petaamperes.
