How the formula works
Both megaampere and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaamperes by 1.000000e+24 to get attoamperes. To reverse the conversion, multiply a attoampere value by 1.000000e-24 to get back to megaamperes.
Frequently asked questions
What is Megaampere (MA)?
A Megaampere (MA) equals 1e+6 ampere(s), a scaled unit of electric current used for mega-scale electrical work.
What is Attoampere (aA)?
An Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
How do I convert megaamperes to attoamperes?
Multiply the megaampere value by 1.000000e+24 to get the equivalent in attoamperes. For example, 5 MA × 1.000000e+24 = 5.000000e+24 aA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+24 is an exact, non-rounded value.
Can I convert attoamperes back to megaamperes?
Yes. Divide the attoampere value by 1.000000e+24, or multiply it by 1.000000e-24, to get megaamperes.
